Rather than have separate limpet controllers and different tools for mining why not have mini ships that are self contained miners .
they could be npc crew controlled or built in AI with the option of specking the build on purchase they could be stored in a fighter rack
the refinery could be built in and the ability to only prospect for and mine required materials and minerals
you could then protect them and bounty hunt at the same time while they mine autonomously
It would be a mining and prospecting kit that only needed a fighter bay and the fighter / miner
