There have been discussions of using the Duel of the Fates theme during the Rey and Kylo lightsaber fight on the Death Star wreckage. Is this something you would consider adding to your list?
With Rey being a nobody does this mean she no longer takes on the Skywalker name? When Rey is on Tatooine at the end and the old hag asks Rey for a surname she says “Just Rey”. This would mean a movie title change as well.
