I love Miz and think he could crossover (not on the level of Rock or Cena, but he has that potential) but he hasn't done it yet. He's stuck doing WWE films and hasn't really branched out besides doing stuff for MTV.
Aside from him, I'm not sure. The thing is they would have to actually branch out and try that kind of thing. I didn't see Batista making it until I saw him as Drax.
So many of them either have no aspirations beyond wrestling* or are stuck in the WWE bubble.
*This is especially true for the women it seems, as the Divas era brought about a bad stigma against women using WWE as a springboard.
