I've been wondering the same as far as choices go for either RAW or Smackdown. Tbh I woundn't mind if Gallows & Anderson go recruiting as well as AJ. But the inevitability here is that Finn comes into the fold, but until that happens I was looking at both show's rosters to come up with a quick list:
RAW
Kevin Owens - He doesn't need to be in a stable and to be honest he's been doing amazing on his own, but as far as some star power KO would be a great way to go, but he seems to always turn on whoever they team him with so.... lol yeah. Two things though is A, I don't see him taking orders because no one tells him what to do, so logically him and Finn would beef over leadership. and B. With the news of Sami being on the same show (despite billing battleground as their last fight), I think they are gonna squeeze that storyline a little bit for the rest of this year.
Cesaro - This one is more for me than him, I'm a huge Cesaro fan and was a bit taken back by not only being drafted to RAW but also how long it took for him to get drafted. He already had his shoot going off on the decision, what better way to bring him in as the disgruntled employee so to speak. If The Club is gonna go against the grain, as heels of course, what better way to make his shoot interview an onscreen statement than to join the team that is going against The Authority/Commissioner/GM.
Sheamus - Again just another need for credible star power here. If Finn takes the lead, and he will, it would be easy for him to recruit his fellow irishman on the team. Though not a fan of Sheamus' promo work I do enjoy his in ring work and poses a serious threat, but I also think he's another case of doing better by himself. Not too mention that they wouldn't really need the extra muscle with Gallows already there but if this is gangland mentality then Sheamus would be a great addition to former BC Army.
Paige - She's been getting kind of royally screwed for a while now, not too sure why or if she's in the doghouse, but if The Club is there to terrorize and takeover then why not side with the winning team? Same case as Cesaro, not too pleased with being on RAW, but could use her frustration with the brass plus the lack of opportunities as a reason to join The Club.
SMACKDOWN
Baron Corbin - Easily could be AJ's new heater since his boys are on RAW, it would give Baron something to do of actual substance instead of wrestling Ziggler every pre show and having squash matches on SD. I know he's a lone wolf and he has an on-screen hate for indy guys but I can easily see AJ convincing the young go hard as to why there's always strength in numbers.
Dolph Ziggler - I can see Dolph getting a recharge by maybe joining the likes of The Club, with his obvious endless losing streak to put guys over, AJ could talk to him about 'guys who bury guys like you'. Plus it seems only plausible that with the way WWE soured on him as being a top guy it seems it would be easy for him to have that continued chip on his shoulder. AJ could remind him of the felonious misuse of his talent and potential to drive the point home. Besides its about time he's a heel again or at least cocky 'tweener, he's so much better as a heel than busting jokes backstage.
The Ascension - Yeah, yeah I know I'll get some flack on this one, but again this is just a case of giving a once prominent talent something more credible to do. I can see either a gimmick change or change in how they present themselves, but you can't deny what they've done in NXT. it just sucks that they can't seem to translate it across to the main roster audience, this may be the answer.
Alexa Bliss - Yes I know she just split from a faction with Blake & Murphy but I could easily see Alexa becoming a WWE stamped Bullet Babe of sorts. I think she has the ability to do well in that type of role. She's already a great heel, she picked that up quick when they turned her in NXT. I can definitely see her coming out to the ring accompanying AJ Styles. Only problem is the Women's championship is on RAW so this would give her something to do other than wrestling the only 3 other girls not currently on injured reserved, seemingly for no reason at all but to wrestle them. Ideally with the Tag Team Title, US Title, Womens Title & the reintroduced Cruiserweight Title on RAW, and the IC Title & World Title on SD! I could see The Club wanting to run every division.
