In Snelgrove's original text 2 and even three box hives are considered so that is no problem. I set a 2 deep hive up this way on june 15. I have 3 med. supers between the bottom box and the division board, then the other box above.
It is recommended that you sort the frames leaving the bottom box with almost no open or capped brood. Almost all brood should go in top box over the board. You could use the method you suggest I guess but have not thought out the implications. I seem to remember something about not having the top box too strong lest they swarm out when the virgin flys to mate.
I have bookmarked some likely looking articles on the use of the Snelgrove board; also have his book, but this is my first shot at actually trying it out. So far the bees started cells on schedule. It was nice of them to place 4 cells on three different frames instead of all on one!
