How about changing R2-D2 'floating' down the stairs to Docking Bay 94 to something like him 'walking' down the stairs in the Naboo Plaza in AOTC?

He's not floating down. Look again, he's walking.

I watched the sequence ten or so times after your post, and you can clearly see (especially when doing it frame by frame or in slow motion) R2-D2 'floating' down the stairs. He is obviously suspended on wires during the sequence to make it look as if he waddles down the stairs.
