Interesting idea. So you can have a squad of “repair” Frigates all tending to a cruiser.
or a squad of speedy fighters dodging fire and repairing a ship.
I like this idea.
Though I think some sort of repair laser would work quite well. With a large recharge time and power consumption but without any need for supplies.
Maybe a play on the fusion beam, where the beam fuses the hull back together, along with bloated repair drones, with better engines and more fuel, that fly between ships, welding as they go.
