A rather radical idea I was playing with: how about making Bail Organa the one who gives Palpatine his emergency powers? It eliminates the need for Jar Jar in the movie, but might also make Organa a bit more interesting character. It would give that little bump on the balcony at the end of AOTC more weight, and would also give him a motivation for starting the Rebellion.

There are some audio material The Force Unleashed cut scenes, voice by Jimmy Smits, that could be useful for this change.

That is absolutely how it should have been. It also adds depth to Leia's efforts as a way to redeem her adoptive father (and a metaphor for redemption of her actual father). As a story-telling device, having the Empire grow out of good intentions and a sincere desire for security is much more interesting and real.
