Well it would be quite hard to keep track on who plays where and how much.
I would instead propose creating additional restart options, based on the Disco story developments of the moment.
For example: Bretonia is going to get steamrolled quite soon: create a /restart bretonia.military, that gives only Bretonia map but some additional pewpew (like a HF or VHF but not the best ones).
And speaking of restarts, it wouldn't be bad to see a /restart zoners or a /restart IMG
