I understand your distaste at the whispered dialogue, but I'm concerned cutting out the enforced concealment of their relationship will take away from Anakin's developing frustration with the Jedi....it's a thread taken up again during the couple's last confrontation "don't you see? we don't have to run away anymore"
Grievous sounds fantastic here! Just sayin'....also, on the topic of the soundtrack, have you considered exploring classical music outside of Johnny Williams, but still within his stylistic range? It may help lessen the familiarity sorta "hey...this music is from that other movie..."
