For sure! The cast so far could definitely use some more spiritual/mystical vibes, and I can't think of a character much better suited for it than GR himself!....Granted I also just think he's rad as Hell (pun intended) 

So for sure run with that if you want! Gambit would also prove interesting, given I know one player is making the son of Storm and Nightcrawler. Gotta love some Mutant rep :D
