Replace Palpatine's ROTJ advisors with Sly Moore and Mas Amedda.

Show what happened to the Empire at the end of ROTJ.

Just curious: have all 6 movies been color-corrected?

I think the ROTJ advisers ought to remain human. We never see any other non humans working for the Empire. I think adding any in would undermine the whole xenophobic, human-only "master race" vibe, which makes the Empire and the Emperor seem as evil as they do.

As for your question, unless Ady has been colour grading other films in secret, then I think the only one he's corrected is the one he's currently fully working on - Empire.
