If you can't cancel the package order, you could pull 3-4 frames of brood from one of your booming hives, make a 5-frame nuc with those frames and the queen from the package, and use the package bees to augment the population in the hive from which you stole the frames of brood. In a little bit, you can install them into a full deep and have three hives!
Or, to keep it easier, just install the package into the nuc.
