A simple concept: target a ship, then a particular subsystem on that ship. Send a limpet and instead of repairing the hull, it repairs that module.
Downsides: This would only work on damaged modules. Anything that hits 0% would still need an AMFU and since you can't target your own subsystems, an AMFU is still necessary to repair yourself.
Upsides: Can repair power plant damage. Doesn't shut down the module while repairing (which prevents using them offensively to disable a target's subsystems).
