I am working on the idea of having mating nucs and when done with them, using them as hive bodies. The shim/bottom of the nuc can also be used as a top later. I am still trying to figure how the inner covers will fit with jar feeders in place and top entrances in the top lid for 2 of the mating nuc slots.
The top lid is adaptable to be the bottom board too and that is where I plan on notching for the entrances, so the body isn't full of holes.. That is my goal anyway, to be able to use this equipment for more than one purpose.
