Only problem with this is… well, the reason Palpatine decided to bang is because he is suffering in a clone body, believing that he would be thriving in the body of a Force-sensitive that is not a clone. His son turns out to be a non-Force-sensitive, and once he conceives Rey, Palpatine goes after her so he would groom her into performing the Sith ritual. When her parents abandon her, Palpatine decides to go after Ben Solo instead, he is the only other person he can groom into performing the Sith ritual.
