I would wonder with him and that new hair style that he would adjust his great wrestling skills to a christian type gimmick, and enforce good morals on other wrestlers, and have a live baptism on Raw in which Kane interrupts and shouts "WHAT THE HELL IS GOING ON HERE!!?".
Aside from the Kane part, I think this is a great idea. I hate swagger, but I think he could definitely pull off a great annoying born-again christian type gimmick. HBK would probably be pissed, but he's retired so whatever.
