I actually did this once this past summer - with a super of comb honey.
I had trouble removing the last of the bees - 30 or so. It was getting dark, I've heard that at dusk the bees will return to the hive. Sure enough. I left the super sitting on top of the hive and returned to the house to put my 'wares' away. I walked back out to the hives about 20 mins. later, all the bees were out of the super, I carried into the house bee-free. Not a problem with one, but just remember, if you're going to do this with a bunch of hives, that means you're working with a lot of full supers in the dark.
