I totally want to promote this idea. I talked about the same things with my mate.
That may fit well with a futur power generator update joaocordeiro mention : core may provide a "computation" (may be a Flops number as used as unit in the supercalculator world) & power generator provide powergrid equivalence.
This will provide a part of the dynamic build gameplay where balance & choice is an important things and allow to remove dumb hard limit like weapon size on core size (the limit became handled by the required flops an item like a weapon will need to work).
We may also imagine a mecanism to shutdown an item to stop its power & computations resources usage.
