Palpatine does not appear. Snoke is the villain throughout (even on Exegol!).
Here is an example: https://www.youtube.com/watch?v=ozgt7T98sVg

That’s insane! The lighting of snoke looks identical and it fits perfect. I actually really enjoy the “I’m all the Jedi moment” but don’t have a place for it to fit into my edits so I’m excited to see what else you got coming.

As to the concept of what you’re doing, I more prefer them to be separate characters, as I really like all of them and don’t want to use one over the other.
