The Maul/Grevious connection was mentioned in the Starkiller Ranch thread. A replacement of the choral music would be interesting. It was awesome backing Palpatine up in Jedi and cool in Dual of the Fates, but it seemed overdone by the time Episode 3 rolled around. I think I'd keep the Immolation Scene music and the choral music behind the water opera, but the rest could go.
