What if instead you had Qui-gon and maybe Mace 'ghost in' at the end of Episode III?
I especially like your idea IF the movie ends with the sunset scene (when Obi-wan hands off the baby and begins his life of solitude). I will keep this in mind as I get closer to drafting the best possible ending.

I added a new production log to the title post, to track and document substantive changes to the original footage, subplots, and chronology. I will try to update it as often as possible.
