It'd have to be much broader in scope to be something more than a novelty... If I'm given a limited number of units in the beginning at one side of the map, then there's only so much possible combination of moves before it becomes a "been there, done that" thing.
It'd be cool to see a World in Conflict-style reinforcement system, and node-capturing strategy from Company of Heroes. As you kill enemy units, capture certain settlements/outposts, and complete mini-objectives, you earn points or cash which can be spent on units/upgrades. Reinforcements should arrive in a certain way, though, so that you don't see enemy troops instantly replenished or doubled in size over a turn... Maybe outposts can act as a reinforcement hub (effectively "produce" units), so after several turns purchased units are shipped in at those spots.
This is a great idea, but I'm sure someone already tried this out... I wouldn't know, since I never played mods
