What 2 do with mini nucs and no cells

[challenger]

I am taking a break from grafting while I concentrate on the nectar flow and trying to keep swarming in check as best as I can. I have 6 double mini mating nucs I have done my first queen rearing in and the queens are ready so is there anything I can do with the population of brood in these mini nucs without having to start all over and restocking them all again when I start up in 6-8 weeks? I suppose I could make some sort of frame holder that would allow me to put 2 of the mini frames in a medium super but all my hive bodies are deeps. maybe I need to bite the bullet and make up a couple of medium splits for queen rearing during the summer.
Thanks

Unless you plan on a large full time queen business, you should probably use full frame nucs for mating. That way everything is usable in your other hives.

Pull your queens let them raise their own queen. Pinch her off when you want to hatch a grafted one, watch that they do not get over crowded.
