Here’s an idea, if you want to try it going forward; what if you used the final trailer’s epic rendition of the main theme, starting when Rey crosses the sabers and the ghosts lift their hands?

It starts at about 1:26 in this video, with the “This Christmas” card.

This music never got used in the film, but I think it’s wonderfully triumphant, and such a great piece that it’s a pity it’s nowhere in the movie. What better place for it than as a great catharsis or denouement for the saga, for it to come in as the grand villain of the saga is destroyed for good by the combined will of the heroes of it. It could continue and come to an end, and return to the original soundtrack, as Finn and Jannah destroy the control ship with Pryde in it.
