I was already working on changing this scene to make it appear that the clones and Sidious were already in league with each other long ago.
Having Cody right away say "Yes, my Lord" when he sees the holo, and then "Yes sir, right away" helps a ton to show there relationship.
Ill try your idea of using the commander audio from ROTJ and see how that works with the parts I've changed. That could really put this little clip over the top as being something alot better than what was originally there.
