Convert deeps to mediums

[Goat Man]

I had a hive that is in two deep brood boxes given to me. I am wintering the colony in the two deeps.
Since all my other equipment are mediums, what are some ideas to make the conversion in the spring?
I do not have any extra drawn comb to use in the spring. So I am thinking about using the bees to draw some comb
for me by placing some medium supers on the deeps. Any suggestions?

I would, in the spring, put on a couple of your boxes as supers, and treat it a bit like a bee tree. There is a nice visual that I cannot seem to get to post here, but it is in http://www.beesource.com/forums/show...ugh-the-winter the sixth post by rweakley.
