Absolutely not. 100% absolutely not.
Punk left for legit reasons and he still holds a very real grudge against the WWE for the way they handled his leaving, and the way they handled his wife. If you are telling me that this has been a very elaborate rouse on the part of the WWE and CM Punk, then I utterly refuse to believe you.
The fact of the matter is that Punk left the WWE on legit bad terms. He has absolutely no live for Vince McMahon, and I get the feeling that the could watch WWE burn to the ground tomorrow and now give one solitary shit. He's done with the WWE. 100%.
How WWE handled his leaving? HE was the one who left before the end of his contract? He was the one who breached his contract? What, because he didn't win the Rumble that year? So Vince is supposed to kowtow to Punk, or else?
Maybe if C.M. Punk showed one sintilla of appreciation, gratitude or humility about all that WWE did for him (made him a household name, made him a millionaire, longest WWE title reign in two decades, and without WWE, he never would have met A.J. Lee, his wife), then maybe WWE would accomodate him more. Apparently, he was a whiner boarding on Bret Hart levels. But while Bret Hart was a chronic complainer, he at least stayed in WWE until it no longer suited him. WWE bent over for Punk, and he STILL wasn't happy.
(By the way, about his complaint about main eventing Wrestlemania, I agree that he should have, but not at WMXXX. I think he should have been in the WM29 main event with the Rock and Cena, and made it a Triple-Threat).
Also, how was A.J. Lee held back? She had a long reign as Divas Champion, and was the No.1 Diva in WWE at one stage. In fact, if she had stayed, she could have been the veteran having matches with tomorrow's Diva stars, such as Charlotte, Becky Lynch and Sasha Banks.
But, no, Punk put his foot down, and she obeyed like a dutiful wife. I can't see Lee standing up to her husband. Shame, since I don't think their marriage will last long-term. A self-absorbed narcissic pantsman like Phil Brooks, who has bedded half the Divas locker-room (e.g. Lita, Maria, one of the Bellas etc) can't remain committed to one relationship and I wouldn't be surprised if their marriage ends because he cheats on her. Then she will have realised that she gave up a wrestling career, which still had life in it, for nothing.
Punk might come back, like Bret and all the others who hate WWE do. They think they can make it out there on their own, when many realise that they can't. Apparently, chronic WWE hater Goldberg is going to come crawling back, so anything is possible. Punk will fail in UFC, and come crawling back to WWE, on Vince's terms. If I were Vince, and Punk wanted back in, he comes back, only for me to humiliate him by making him dance to the ring in a tutu, and job to everyone, to make him an example of what happens to those who bite the hand that feeds them.
As for Lesnar, if he wants to go back to UFC, let him. He is never on TV anyway, so he won't be a loss. Then, when he gets beaten and leaves UFC again, with his tail between his legs, like last time, he will come back to WWE, and hopefully earn his money wrestling every week on RAW, Smackdown and PPVs, like everyone else has to.
Maybe WWE should let Punk and Lesnar get UFC out of their system, and then when they get humiliated there, they can come back to WWE and be re-branded as a tag-team- a 21st century version of Chuck and Billy or Lenny and Lodi. LOL!
