OK- What if...in Empire Strikes Back: Luke joins Vader to destroy the Emperor??? Vader said he would complete Luke's training...(That whole scene makes sense now after seeing episode 3 - how Anakin is obsessed with "ending the war" and "returning order to the galaxy..." What would happen if they DID kill Palpatine?! Would Anakin bring balance and turn good again...maybe "retire"? Would Luke make him be "good"? Or would he just pick up where the Emperor left off and keep the Galaxy in check? THAT would be a cool fight, too! The Skywalkers VS Palpatine! But where would that leave Leia??? Would She be trained as a Jedi and take them both down? Hmmmm...
