It could be ideal even subtle as death adding the iconic background sound that appears in the throne room in ROTJ (and somewhere else in ESB) to places like when palps gives the name to DV or to any senate rooms.
@The Cutter. I just notice that you crushed the levels in some of the frames when Palps hitting the lighting bolts. I really loved that! Keep these surprises coming. I also noted that you were add real lightning/storm sounds. I had to say that because i had this idea when i wanted to propose ideas for ROTJ. I like your way of approach ;)
I agree with Bingo that you should try redubing when is necessary. Especially to palps gimmicks.
Taking ideas from Brash_stryker's topic you can make clones sound more like OT. even adding the clicks when a sentence ends behind their helmet(as we see in ANH)
I can provide clean plates if you want as Tobar said. ;)
Use no limit as limitation!
