That looks like a great idea... I had a similar idea, except it included making a "bee vac out of an open bottom, but closed top shallow super, then attaching that super onto a deep hive body with frames and everything (I don't know that it has to have drawn comb, but at least foundation for them to walk on)... Seal that up with come duct tape, and place a solid board under it, and attach that to the bottom of the deep with duct tape as well to seal it. Then just strap the whole thing together and you're ready to go. Might be a little heavier, but I think it would still be cool.
Could even put a feeder in... or whatever else you want to help them transition. Once you're ready to set them up, just pop the whole thing onto the bottom board you want to use (swarm) or hive body(s) that you put their own comb in (cutout), undo and remove the straps and duct tape around the bottom... then just slide the bottom off the bee vac and let them readjust to their new home. In a day or two you can come back and remove the bee vac from the top and put a proper top on.
What do you think?
PS - One problem I can already see if doing a cutout with it would be keeping brood comb from getting too cold with no bees on it... for that, the only thing i can think would be to put the capped brood in one of those heated coolers that's set to just the right temp. to store it 'til you can get the bees back on it in a few hours.
I can't think of any other problems with it though, can you?
