The dark side is supposed to be seductive, yet Lucas never went and made any dark siders seductive themselves; they all looked old, or deformed, or stereotypically Satanic. I would have done the opposite. I would have cast a woman as Palpatine - preferably young and at least moderately attractive - and brought back Clive Revill to do Palpatine's voice. Instead of snarky and sarcastic, Palpatine would sound calm, sauve, and at times even genuinely remorseful. He would be this great dark father - mother? - figure.
A sexy Clive Revill Emperor would have been very cool/creepy.
