[Star Wars] Assuming Palpatine succeeded in mastering Force-Immortality and killed off the Skywalkers, what was he gonna do with the Galaxy?

Build up more control until his New Empire controlled the entire Galaxy, build up his own Sith Alchemy and Force Powers to levels exceeding those of the Mortis Gods, find a new apprentice to handle the enforcement of his will, and expand past the borders of the Galaxy to conquer worlds yet undiscovered.

There wasn't much else Palpatine wanted. He'd definitely look for another way into The World Between Worlds so he could time travel and fuck with the timeline, notably killing or capturing Jedi rivals of his like Windu or Yoda so as to take sadistic pleasure in torturing and or killing them.

Beyond that, capturing all the Jedi Temples and Holocrons would be a side quest for him. Enslaving and corrupting Force Sensitives as well (broom boy would be snatched up). Anything supernaturally unique would also pique Palps' interest (like Mortis, the source of the Cosmic Force, etc)
