Repair capabilities in SEV are measured by tonnage repaired per turn so all you would have to do is scale down the amounts for unit repair.

If I'm understanding this concept correctly each unit would represent a larger group and the components you put on the unit would represent individual troopers or vehicles. That would be cool as long as you remember to also scale up the costs so that you couldn't build an entire "army" in a single turn.
