as horrible as this sounds he'd probalbly have ben affleck or pierce brosnan as han solo and matt damon as luke skywalker. He might even use nathan hamill to play luke. Leia would be played by charlize theron, natalie portman, or Kyiera neightly. Lando played by sam jackson. Obi wan ian mckellan, ian holm, derek jacobi, or patrick stewart. Vader would still be james earl jones, to me the only other choices would be orson welles, or brock peters who are both dead. Dave prowse in the suit not christenson. don't know of any actor who could be tarken, would have to be a really creepy hatchet faced guy. That girl from cheers could be jabba. Boba Fett would have to be played by some badass actor, don't know who.
