[Star Wars] What would happen if Palpatine had been killed by the broadside from the Venator on the Invisible Hand in Revenge of the Sith?

Everything before that point is the same, but the broadside that hit the Invisible Hand kills Palpatine. What happens?

Considering the proximity, odds are good that Anakin Skywalker and Obi-Wan Kenobi are also vaporized.  Depending on the timing, General Grievous might also bite it, so that’s four major players down in one shot.  I’d hate to be that clone gunner...

Anyway, unless there’s some contingency for his premature death (not likely, given his profound arrogance), the plans and machinations of Darth Sidious die with him.  A successor is nominated by the Senate while the Jedi take control of the armies in the interim, and the war eventually ends with a vastly higher chance of a diplomatic close.
