If you go the route of Anakin dying in the temple, I think it’s required to keep Padme dying. After all, Anakin’s primary temptation to the Dark Side in ROTS is to save Padme from certain death, at least from his point of view. Her death comes as a dark vindication of his visions, and keeps Anakin the noble hero of a tragedy. If she were to survive, the movie would descend into thematic incoherence.

The crawl could provide the blueprint for this new direction, setting the stakes as a battle for the soul of the Jedi religion. Set up Anakin as a Lancelot character, the best of the Jedi Knights whose moral success or failure will determine whether the Jedi as a religion deserves to live or die. Then the Sequel Trilogy could gain more essential relevance.
