Oh, if they really want to piss of the fan base they could go the whole "Triclops" route with the First Order/Final Order/Imperial Remnant trying to assert power through Palaptine's "son" (aka clone) as the "true heir" to the galatic throne.Something just dawned on me, since the movie had the flashback with Rey's parents, and Rey's father is a clone of Palpatine, that means we could have an actor for a younger Palpatine if they ever want to use the character in a movie or show set before The Phantom Menace.
I always found Palaptine's son to be an interesting path to travel.
