I might try to make an example later and see what it might look like.

If that doesn’t work or seems too different, another option could be to remove a few segmented panels out of the dish itself, which might achieve a more subtle change that it could still make it feel incomplete. Although it might be less effective than completely removing the dish, it’s a potential middle ground.

Regarding the Luke hologram, I think how you handle it sort of depends on your interpretation of Luke’s plan. Do you want to keep the fact that Luke gifted the droids to Jabba, since it implies he wanted to get R2 in there? Or maybe he was betting on Jabba just keeping the droids for himself.

Could the message just be R2 beeping a bit to them (maybe with 3PO chiming in with surprise that they’re the gift, rather than the hologram. Then, you could add/change Jabba and Bib’s subtitles to provide the context: Luke wants to bargain for Solo’s life and he is gifting the droid’s as a token of good will.
