It might not be so bad to just put the unused music in TFA instead. I wouldn’t have to do a new render, just audio and remux, and then distribute. If I go that route, I would probably wait for TROS to be completed just to make sure there’s nothing else to do.
If I can tonight, or whenever, I’ll mock it up to make sure it doesn’t, y’know, ruin the TFA moment or anything.
