I wonder if you can 'fullbring' people. I know people aren't objects, but they can be your pawns. like everybody was to Aizen and everyone is to Kisuke.

maybe you can put the people you fullbring in little balls and carry them around to do battle, that wouldn't be much stupider than saying "he fullbrought the concrete, and then the random molecule in the air", few chapters after you've said that you need some sort of connection to the object you're trying to fullbring.
