me and my frieds in our litte german SOW community had an idea for a simple MP campaign playing MP Battles on an selfmade strategic map. We built a strategic map simply with Windows paint (i will show you the map next time) and wrote our own Game Rules. You have to recruit new troops and conquer cities.
You get (for example) 500 Recruits per round. Normal Infantry costs 1 Recruits Point per Soldier, Cavalry costs 2 Points for one soldier / like sharpshooters and so on. The troops can move on the map.
If you meet enemy troops on this map, you will have an fight in SOW. (Only problem is, that there are only a few maps for SOW..but we use our fantasy

Its much work to save the results (on paper) an create new OOBs for every battles with Gariers OOB Editor. I have created an "Master OOB" with all units on the map for both sides and were i fill in new troop strengths after a battle. (free Infantry brigades, free cavalry brigades, garnison troops, Divisions, Corps and Armies). Before a battle i built a "battle OOB" with the needed troops. And so on. You have to gain Victory Points (with conquering cities an win battles).
Also an idea was, to change the experience in that way the units are organized. Better organized troops habe more experience. Example: 1 Brigade has 8 experience, 2 Brigades only 6 exp...3 Brigades 4 exp...and so on.
If there is an higher organisation (like a division) the experience of more units in a city will grow. So one Division with 2 Brigades...both Brigades have 8 Exp...
So, its much work to programm the new OOBs and to change the Map in Paint, but its very very very fun.
I would be happy if here are any people you are programmer (like Garnier) who can create a Mod like this for MP Battles on an strategic map.
