Honestly, I don't know what to make of this, because it's one big mess, that's all that it is.
There are a lot of reasons, as to why this is a terrible idea..
Last year in made perfect storyline sense, to have Bryan win his title match by force and go on to headline Wrestlemania against the whole Authority/Evolution, overcome all odds, and win. This year though, Bryan comes back and enters the Royal Rumble. And those pigs in the booking team, make him look like a complete rookie.
If Bryan gets in a triple threat at Wrestlemania after that, then, why not add the entire roster in that match and make it a battle royal, since every guy that competed in the Rumble can now get a legit claim to the title.
Yes, I get it that Bryan wants a rematch with Lesnar and that he never lost the title. But they never really got this in the story, because they wanted us to forget it. So, even if Bryan gets inserted in the match, using that claim, after being in the Rumble and after going through Rollins to earn that shot at Roman Reigns, it makes him look like a phony.
Also, how are they going to add Bryan into this? Isn't the Authority the one that makes all the decisions? Or maybe they'll have Vince come back and add him. But, doesn't that make Roman Reigns a fool? It does. He will come off like an idiot.
As for Roman Reigns, what happened in slaying the beast? Triple threat match to slay the beast? No way. Undertaker himself should come back and beat these guys in the creative senseless if that happens, because the biggest rub in wrestling history will be wasted. Just like that.
Vince knew what was going to happen at the Rubmle and he did nothing to prevent it. He ran with his idea and you know what, since he ran with his idea he should also finish that idea, instead of making everyone involved in the storyline look like crap and completely illogical.
Do they really want to save this mess? There's only one way. Reigns losses, Rollins cashes is and we get Bryan-Rollins and Reigns-Lesnar at 'Mania. This was what should have happened at the Rumble, they can still run with it, do it. If you want Bryan at a title match and Reigns vs Lesnar, that's the only way. Bryan beats Reigns, next night Lesnar calls Reigns out, saying he is all talk and nothing more, Reigns beats Lesnar with a chair, Rollins cashes in. Just like that.
Or they could just run with the original idea and accept the consequences. Because who knows? Regins really became more likeable after the sit-down interview and could become even more if those idiots in the creative team can find something to really make Lesnar vs Reigns the biggest war/match we'll ever see on wrestling TV and not just rely on Reings/Lesnar's badass looks and Paul Heyman's insane mic skills in order to sell the event.
EDIT: Another interesting thing they could do, is book this like Wrestlemania 10, maybe? Bryan beats Reigns Sunday, Wrestlemania: Bryan vs Ziggler/Sheamus in the opener, Reigns vs Lesnar midway, Reigns vs Bryan as the main event.
