The only flaw being, if one is a dud, or if the Kazon somehow manage to disable one in time, now you've given the Kazon extremely advanced weaponry and altered the balance of power in that part of space
then put multiple tricobalt devices on there. dozens. however many it takes until there's enough to satisfy your silly theoretical "what ifs"
but, remember: when the Kazon got their hands on replicator tech, the worst they ended up doing is turning themselves inside-out and half-fused with metal. I'm not too worried about what would happen if they got half-exploded Caretaker tech. They'd prbably turn themselves into a folksy barbeque.
