I think this proposition is incredible.
There's not much that I think I can do to physically help, but, either way, I would love to help by inputing thoughts/ideas throughout.
One idea I would like to push forward right away is that I think there should be a goal to keep this edit 120+min. Many, many, ROTJ edits are under the 120 mark, and it really hurts. This is the epic conclusion. It needs to have a runtime suitable for a Star Wars film.
