if you want to re-write the prequels, you have to consider re-writing jedi as well since he didn't stick to his original story for that one. You basically have to do the following: kill han toward the end, no death star 2, no ewoks only wookies, luke and leia are not related, don't show the emperor. at the end han dies, leia becomes queen of the remaining people of Alderaan and Luke goes off to find his sister. Chewie and Lando do something, probably go with leia I guess.
