I know you’ve used the titles of TFA and TLJ for your sequel trilogy Hal, but have you considered a new title for this one? The Rise of Skywalker just doesn’t convey what this movie (where the Skywalkers go extinct) is about.
My suggestion - Heir to the Empire. The film is about Palpatine’s heir and trying to decide whether it was Kylo or Rey. It’s a classic Star Wars book title, thus fitting with PT naming choices. Plus it gives a good ol’ George Lucas level rhyming scheme to the names of each Trilogy’s Climaxes.
Revenge of the Sith
Return of the Jedi
Heir to the Empire
I think the “Skywalker” the title refers to is Rey. Having said that, I’ve always thought “Legacy of Skywalker” would fit better.
