You summed it up a whole lot better than I ever could've. And your idea to revive Bayley's character sounds like something I can get behind. (Personally, i'd also consider giving this role to Mickie James, she does have the vet credibility that would make it work)She's not doing badly at all... you get a turn, but it's not a long one these days... that's the reality of life as a champion in WWE... it gets changed up far quicker than it ever did... if you get a solid 3 months, you've done well.
Bayley as a gimmick is in the same situation that Adam Rose was when coming up from NXT... the smaller scale and relative freshness of the gimmick in that setting was what got them over and the "smarks" interested to be chanting "this is awesome" etc...
The problem is, by definition, those gimmicks are the ones people hate most on the main roster... and are almost now conditioned to thanks to Cena and Roman...
Bayley on the main roster is going to be as dull and hated as Cena endlessly playing "goody two shoes" or Reigns trying to be the babyface hero... The sad thing is the gimmick does fit Bayley far better than it ever did either of those two guys... but they've ruined it for everyone...
When WWE has used women in that role before, like Molly, there's normally a wrinkle to it that makes them a heel...even when it's the guys like Kurt Angle or the Right To Censor who are being "whiter than white" they were heels.
For a face "goody two shoes" who isn't being a heel, at least under the radar, there aren't too many great stories they can have... it's either an underdog chase/redemption arc, which they've done or... the obvious relationship angle... perhaps that's where her "acting" would be exposed most... it's also quite awkward to play the whole "Never Been Kissed" angle they seem to want to go when she is known to have a boyfriend off-screen (and gay as a lot of morons seem to assume.)
Pretty much any other story forces her to become slightly heel in some way, which they don't want...
Is it unfair? perhaps as Bayley IS great at what she does... but while everyone saw Charlotte being a star (and getting more leeway cos of her lineage) and Sasha and Becky being the big names when they were all in NXT, people forgot Alexa was there... Her rise has been a bittersweet thing for WWE... they now have a cracking heel for their women's divisions... but their big face hope seems to be the casualty of that... they can't push Alexa as a strong heel for the future AND Bayley as the face version at the same time... they've chosen Alexa, rightly in my view as there's more potential for stories...
The way to get Bayley back on track is to bring back Molly Holly, or at the outside Beth Phoenix as a manager/mentor who encourages her to fight/gains her trust and then turns on her, a bit like Karate Kid 3. That would give Bayley a reason to become tougher/more ruthless as a character and have more of an edge to her career going forward... fool me once etc...
P.S: I just now saw this article about how to revive Bayley's career and I figured I share this with you and potentially discuss about.

My Opinion: The idea of having Bayley potentially returning 'home' to NXT sounds like an intriguing idea on paper, but the idea of Bayley losing EVERY match until she gets demoted sounds maybe a little too risky.
So how would I go about it?: Well, with Emma recently returning; you could have her feud with Bayley for a little while, telling her that she 'told her' she would struggle like she did on the main roster and get into her mind a little bit; at first, she doesn't seem to notice and keeps doing her thing, but as the fans continue to turn on her; she begins to start to struggle. This is not helped by Emma tormenting her with mind games.
From there, something snaps. She challenges Emma to a match at whatever PPV comes next and she accepts. The two compete in a good match, but it seems like Bayley is holding back; and this ends up costing her the match. The next night, Emma verbally tears into her; proving once and for all that being nice may have started out fun at first, but as time passes, it turns out to be her kryptonite and what ultimately will keep her from ever being what she could have been.
Suffering from a loss of confidence, Bayley begins to question whether or not she can do it on this level any longer; the losses continue to pile up until she finally hits rock bottom. To do this, you get Izzy to come over and admit her fandom to, say Alexa Bliss. That's enough for her to breakdown in a pile of tears as a friend of her's (Sasha Banks most likely) goes to comfort her.
The next week, a solemn Bayley comes to the ring, no inflatable buddies, no hugs, no nothing. Instead, you just get normal Bayley. She gives a passionate speech on how much she loves wrestling and loves fighting for the fans, but realizes that she can't keep letting her fans down any longer.
And then, the bombshell; she reveals that she went to Triple H's office and openly requested to put her back in NXT. She explains that this move would help her find her 'killer instinct' that she now admits she lost along the journey upward. But she assures herself and the fans that one day, she will return better than she ever was and thanks them for all their support. She leaves the ring, hugs a few lucky members of the audience...
And poof! You have her go to NXT, have her fight some of the girls there and after sometime has passed, you either bring her back for Survivor Series or just after Wrestlemania season as a more serious, more ruthless, but still lovable competitor.
But again, this is just one way to go about it; you guys have come up with a lot of great ways to revive the Bayley character and I truly am happy that we're having this discussion right now. As someone who wants to go into writing in the future, this really has helped the catalyst that sparked the 'road to redemption' storyline for Bayley. The one you just now heard.
So, why stop there? Let's keep going and enter in the Hug Express and keep this debate/discussion/bi-curious wrestlefest going for a little while longer.
