Very nice! The morph effect is seamless.
The "so be it, jedi" gave me another one of my crazy ideas. It would be sweet if, after the lights go out, Palpatine fries the other three jedi with lightning. Leaving only Mace. Then the lights come back on momentarily, and the Mace and Palpatine fight starts. It's probably not possible given the available footage, but I can dream.
