You know what would be a good idea, controlling a rebelious group. As you said georgia is a part of the soviet union, why can't you control independence rebels in the area.
Here is the idea.
The units will be spread out, and have a stealth bonus
Most of them will be millitia, but there will be one commando unit
You will have extremely low resources, which makes offensive movements very hard
If you manage to capture a city, you can produce whatever you want there
Each city will have a popularity for the rebelious group, as in the stated example of georgia, georgia cities will have higher morale when the rebelious millitia capture them, but say like a city like kiev, capturing it will not have a morale boost
It is a great idea, but it is just an idea, probably never going to be implemented SAD
