I have no real skill with editing, but I am going to try my hand at an (initially anyway) simple goal- reinserting the Biggs/Tosche stations scenes into the movie. That’s my primary goal and i’d be happy with just that.

My “stretch” goal, so to speak, is to cut out another scene that the Biggs scenes mostly make redundant- the “It’s only one more season” dinner scene (at least the parts that repeat the information from the Biggs scenes).
I’ve become convinced (this might be a common filmmaking thing, I don’t know) that Lucas had multiple scenes telling the audience similar information (not only the two i’ve been talking about, but also the redundant information in the Han/Jabba SE scene) in order to be able to really shape the film in the editing room by giving himself multiple attack vectors.
It is for this reason that I think some of the dinner scene can go without losing anything- I think it was designed to.

Any thoughts on my ideas?

P.S.
The other two stretch changes I would make would be to delete the Jabba scene (I’d be working off the Blu Ray), and to alter the colors to make them look less garish.
