While the idea has merit, the current design of the game does not mesh well with it. I've already made similar suggestions regarding the shortened timer and "ticket-based" system for DM-launched snubs, that have received similar responses.
Basically, for this to fly, you'd need to redesign it into a completely new game, making snubs squishier when faced with caps and each other. Unfortunately that seems to be the complete opposite of where the mod is currently heading.
But there is one thing that could be improved, and that is to shorten the docking time a bit to allow more use of combat docking, like in the old version. I think it's now set to what, 11 seconds ? In any case attempting to use a DM in a combat situation now is only going to cost both the carrier and your snub more nanobots / hull damage that you'd "save" from a free repair.
