I suspect you don't want to go back over the first 70mins but I had an idea to insert a shot from a making of documentary into the mos eisley scene, its probably too harsh a shot to look nice but it would be the zoom shot onto the jawas at around the 12.42 mark in this doc., inserted in place of the still shot of the exterior cantina, right after the cross cut to luke after ben's dialogue "..weak minded".
