The Biggs at Toshe station scene could be used to make things a bit more clear. The dialogue could be altered to state that Owen has a "Moisture Farm" with condensors. The situation could be more clear, earlier. Maybe change "Nationalize" to "Imperialize". The scene could begin with the gang viewing the battle.

I think someone mentioned turning Jabba into a hologram. Maybe the ROTJ footage could help with that. Greedo-Han and Jabba-Han could be recut to be more consistent and less repetitive.
