So you have four five frame deep boxes on top of each other full of bees right? Just set down two bottoms and deal the boxes. One for you and one for you. Add two more empty boxes. Or, if you're moving them to ten frame boxes anyway, deal the frames into the boxes. One for you and one for you. If both the new ones are facing the old they will even out pretty well. The one with the queen will always have more bees in it... but in 10 days or less you could reverse the boxes. Don't reverse them after that because you don't want the queen returning from mating to go into the wrong box.
