Why re-record or replace any audio? Just clip the laughter off the end of the eyestalk's line and be done with it. Scanner effect would be nice if it was kept short and sweet...doesn't need to happen during the whole dialogue, just at the beginning.

I actually quite like the idea of it being on during the whole duration (though it should rotate, I should have traced some impact lines on the droids but I thought the illustration was enough to get the idea across).

There could be some fun to be had by adding a scan hum (a bit like the one used in the beginning of Aliens) or a whoor-whoor noise like the one in AOTC when the scanning laser is protecting Padme with R2 in the room.

Sluggo I love the idea of making it more abrupt (I don't speak Huttese and I'm sure neither does most of the audience) it might be possible to filter the existing material some more to make it more mechanical (the good ole ring modulator perhaps?).
