It’s a fine line to cross. Because on one hand, TFA and TLJ have done a really bad job setting up Kylo as the villain. He’s a joke, and shows little fear. In a perfect world, this would not have been the case (at least for TLJ).
I think a better option would be to create a new villain for TROS. Maybe a “Dark Whill” or Force God that is responsible for the dark side, hence greater than both Palpatine and Snoke. I agree Palpatine was a bad idea.
