Gotta say, not liking these stable ideas.
Only thing pitched so far that I'd go for is pairing him with Abadon which would probably not be an act that I'd actually enjoy, but it does at least make sense and keeps Wyatt from tainting other acts that I do enjoy.
I'm not with him taking over Butcher, Bunny and Blade, unless his next character is more of a Bond villain persona. The cultish/supernatural thing wouldn't apply to them. The Butcher explained their act as being like the initial hired guns that get beat in the first act of a James Bond or superhero movie. It's gimmicky but it isn't mystical, so they'd have to be able to rectify that somehow with Wyatt. Personally, I just prefer they continue as the HFO muscle because the dynamic is already there with Big Money Matt being a rich, dastardly villain who has others do his bidding.
