I don't see some of them falling for it so easily. The way I see it, Joker would know if that's his greatest adversary, the same with Ra's and maybe Deathstroke. And Sabertooth would know from the first scent, and the rest of Wolverine's foes when they notice that he's not short.
Anyway, mismatches for all, whether they team up or not, with some trouble from Juggernaut.
