Exactly. Then while Palpatine is in the middle of saying "no" repeatedly, show Windu lift his lightsaber in the air out of frustration, like he's going to kill him just to shut him up.

Come to think of it, I think Anakin might scream "No" somewhere around there too. The whole thing can turn into a big "no" fest

List of "No's" that could be used:

Obi-Wan's no from TPM

Qui-Gon's no from when Anakin slaughters the sand people

Darth Vader's infamous no (to signify Anakin's fall to the dark side)

and of course a repetitious no from Palpatine.
