While they're usual style might not fit well with CHIKARA values, I can see them hamming it up nicely, as they're all pretty good characters to put over in a comedy/family environment. Obviously, no big Hardcore spots will be done, but I still think they'll manage some funny antics.
I'm sure they'll be just fine. I think them vs. F.I.S.T. would be perfect, with Necro and co. just brawling and mugging them, while the rudos run around crying and hiding.
