Would need to look at the sequence again but I think there’s enough material to work with, Maul falling down the shaft could be done just by using the beginning of his fall before the split and cut to insert of Kenobi’s reaction then back again to a composite of the empty shaft. Re-timed this wouldn’t even need a score change everything moves fast already.
I think you’re right on this, that shot should be long enough to trim in this way. It’s definitely worth attempting. I may give this a try myself soon, once my setup is viable for editing.
I wonder if any of Sam Witwer’s Maul lines could be added here also, to have Maul goad Kenobi at the end of their duel, and help sell the transition to Clone Wars Maul. Though perhaps that would be too much to add this here?
