Make this easy for you: No
Lol.
Stillmdoesnt change the fact Punk has failed as 1B himself. He had a hot streak but he doesn't sell ppvs or draw viewers, actually loses them without a Cena or Kane type across from him. Some of his quarters and over runs are horrid for a guy with the lengthy run he has had.
He isn't made himself and that to me is just the problem.
The WWE title and making a main eventer has never been about two guys who aren't top stars making one another into top talent with their work. It ain't how the company has worked ever. Hogan cemented Warrior. Bret cemented Michaels. Michaels cemented Austin. HHH cemented Batista and Cena. Rock cemented Brock. Hell HHH did it with Jeff the right way and he was more successful on top and had a higher ceiling than Bryan or Punk
Yeah Punk beat Cena, but it wasn't clean and it amounted to jack shit. He has had feuds with Del Rio, Bryan, and the like but it has gotten those guys or him nowhere. Hamster on a wheel. He can't make a guy when he isn't credible enough and made himself, which is partly WWEs fault for getting him a fucking transitional B list at beat guy to headline Mania with in Jericho, as a win or him meant jack shit on the grand scale of things.
Kane no matter how you feel about him, no matter what he has done, the goofy shit, Katie Vick, and the like is still a legitimate and importing threat at any given second. The same goes for Big Show. They can just be flipped on like a light switch and be taken more seriously than Jericho, Punk, Bryan, and so on.
If you want to build a future you go out and take one of Cody, Dolph, Ryback, or Bryan with a tweaked gimmick of the guy we don't name and place them in a situation to chase Kane, Show, or the Man in Cena. You have them follow the path of guy who gets closer and closer, does better, and gains respect before getting hat big win. When they then get the big win for the strap, you have a legit champion with staying power who people don't change the channel on just like they had in 2005 with Cena and Batista, and just like they had when Jeff got the belt.
Punk ain't cutting it. Bryan ain't cutting it. This formula of hoping they somehow wrestle their way while covered in smark filled jizz to both being legit is garbage. It goes against what the company was built on and what made the WWE special whichis why you see the champion and challenger on the middle of Raw and not headlining multiple ppvs for silly ass gimmick comedy matches
