sure. you can shake them all out in front of your other hives. remove old box so they don't go back, and they will join other hives.
i use window screen instead of newspaper for a couple of reason. 1. if i'm wrong about a hive being queenless, i don't have two queens killing each other and 2. i have lots of old window screens :-D last year, for example, i had a hive that i was pretty sure had a virgin queen, but i could not find her. enough time had gone by that i was concerned about developing laying workers if there was not a queen. i put the hives together with window screen between and top box with it's own opening. in a week, i checked back and found a laying queen. no queen loss, no laying workers if she hadn't been there, and easy to pull them apart again.
