Just watched the TROS documentary and I think I spotted a few extended shots here and there that could be used, Luke and and Leia’s duel could be extended, an alternate take of the “Rey skywalker” delivery with Rey crying as well as a few shots of empress Palpatine on the throne, extended Rey and D-O, kylo on passana, kylo placing Vaders helmet etc.
Yes, I really liked that take of the Rey Skywalker scene, she said it in a more solemn way. Maybe we could keep the tear too.
