Totally valid. I was just thinking in the context of what could be done with a less ambitious rearrangement of existing elements.
In that case you could merge Starkiller Base and Exegol, and instead of the superweapon aspect have the remnant Imperial fleet instead, maybe keep it being an ancient Sith world in order to tie it better to Snoke or the Knights of Ren even if Palpatine is not present in this.
