i like the idea of jedi being set years later.
i reckon the success of this film though rests in the radical changes made to the PT aswell. whoever comes up with the best idea will need to lay the foundations and plot strings back then.
if jabba was a more important player in the PT for instance, the han solo mission could have a two fold purpose (reanimating lots of droids for example).
perhaps the endor bunker could be the droid control hub?
