Since the first big version of Ascendant is sticking with Rey Palpatine, I wish there was a moment in the film where we had a version of the Emperor’s theme, but with a female choir. Like maybe you could hear it as Rey is entering the Exegol temple. But I don’t even think a female version of the Emperor’s theme exists anywhere. Or even a dark side version of Rey’s theme.
If you have a specific version of the Emperor’s theme that you like, I’d be happy to add a female choir on top of it doing the melody. I just wouldn’t want to have a non-John Williams track in the movie, so I wouldn’t do a track from scratch.
