For those who are experimenting with overwintering nucs, check out this link:

I found it yesterday and thought maybe you haven't seen it. It talks of using a vertical screen between the nuc and hive in a trunk or chest like hive. Frames are 1 & 1/2 times as large as our deep frames. Not alot of info, but might get you thinking.
