Just a suggestion, but do you think you’ll remove the reveal of Rey being Palpatine’s granddaughter at this point? I know that there are moments in the film that play towards this narrative, but they (like Palpatine offering her the rank as Empress) can still be kept in with an altering viewpoint and motivation.
He could offer her the throne knowing how powerful in the Force she is and ordered for her and her parents to be killed knowing her raw power that could potentially be a threat to him.
Her being his granddaughter does raise so many unanswered questions, especially who and when did Palpatine married to have a son. I’ve always liked the aspect of Rey being a nobody and rising (no pun intended) to become somebody worth of recognition. Even the ending of her doning the name Skywalker would make things even stronger without her being related to the Emperor.
