The stories of the Sequel Trilogy don’t hold up because they are completely disconnected from the original 6 movies. The attempts to reconnect them by bringing back Palpatine (and making Rey a Palpatine) did not do enough to build an actual connection. They are also generally paced terribly, all three. Rise of Skywalker should have released as the 3 hour version; assuming that happens at some point, here is my proposal for a reworking, that could possibly be done as a fan edit:
Episode 7(no roman numerals because its too hard for normal people, and it signifies a certain departure and non-continuity, and its nature as a sequel to a series of 6 movies): Shadows of the Empire (It is just a good title, forget the book or whatever)
The introduction should be rearranged to flow better, and the comedy (and cringe scenes) should be cut. Acts 2, 3, and 4 out of four should be greatly truncated, time skips are acceptable. The second half of the movie should be devoted to all of Luke on the island, and a greatly truncated half of the Last Jedi, ending before Krait.
Episode 8: The Last Jedi
Begin with Krait, and end 1 hour through the Rise of Skywalker.
Episode 9: The First Skywalker
Finish out RoS, end with a scene showing Rey going back and time to be Shmi Skywalker. Cut from “there was no father” to the part where Kylo Ren is force healing Rey, with his hand on her stomach. It won’t be a good ending, but it will be an ending, and it will tie together the whole saga (not so) nicely (which is better than not at all). Maybe somehow have a real Sky-walking scene or something, this could have been Kathleen Kennedy’s idea for the ending. I dunno, who cares. Who cares is better than “I don’t care.”
