#2 Stone Cold Kevin Owens

This is technically not one gimmick, but two.
However, as Owens is one of my favorites, and this is my list, I'll allow it. Besides, nobody can deny that he needs a serious reboot after spending the last few months as Braun Strowman's punching bag.

Owens is done as a credible heel. A babyface turn beckons. Quitting RAW last week would have been the ideal way to achieve this reboot, but I digress.
Remember the Daniel Bryan storyline from Summerslam 2013 till Wrestlemania 30?
The authority did not want Bryan as champion because he didn't fit their notions of what the face of the WWE ought to look like. So Bryan was held down. The Authority berated him. They cost him championships. And they helped create the biggest babyface since Stone Cold Steve Austin.
I propose that Owens become a sort of hybrid between the two.
Have the authority cost him a championship because they do not want him as the face of the company. Explain away past favoritism by pointing to his losing record. Have them berate his weight, scruffiness, and ring gear.
Paint Owens as an every-man fighting for his dreams. Let Owens' clarion cry be that it isn't outside that counts, but a person's mettle, thus creating a babyface parent's are supportive of, and kids are proud of.
Let him reject the authority's attempts to mold him into the sort of champion they want. And let him stomp mud-holes into everybody.
Owens has the mic-skills to pull of such a character, and the story is believable enough to be accepted.
Also, if any more proof were needed, that stunner to Rollins on RAW 2 weeks ago was something Stone Cold would have been proud of.
