I would not object at all to discarding the last three films, and start over.
The original Star Wars movie told a good, coherent story. Expanded into a trilogy, it told a bigger, good, coherent story.
The prequel trilogy possibly suffered mildly from a condition that I call “Pandorum” (after a movie by that name, which I consider the model organism for the condition, viz., a basically good story stretched way too far), but it told what was basically a good, coherent story as well.
The sequel trilogy is a mess. One gets the impression of episodes 8 and 9, that each was made by someone different, who didn't pay nearly enough attention to what was built in the previous movies in that trilogy. Within each movie, its part of the story makes sense, but the three movies as a whole, do not. And bringing back Palpatine, as they did, seems like a rather ridiculous variant on the deus ex machina principle.
I wouldn't at all mind seeing a whole new sequel trilogy made, ignoring the mess they made of the previous attempt, and written in a more coherent manner that tells a meaningful story across all three movies that compose it. I don't even particularly see a need to redo the first one. The Force Awakens was a good enough start. It just needs to be followed by a movie that pays more attention to it, and builds on it in a way that The Last Jedi really didn't,and then that needs to be followed by a movie that likewise pays attention to the two that come before it, and builds on them, in a way that The Rise of Skywalker really didn't. And Palpatine needs to be left dead, as he was at the end of Return of the Jedi. And I'd really rather have seen Rey turn out to be of the true Skywalker bloodline.
