Can I add some suggestions?
I believe the scene where C3PO is tangled in the wires on the falcon was actually shot for the beginning of the film. It would go at about 4:28 in your edit so far after he and R2D2 make it across the battle scene without getting blasted.
Also the Lost Cut is supposed to have a documentary feel with lots of scenic shots. You may want to add some desert scenes from other films.
And you may want to remove matte shots with images like these:
