Looking for tips and suggestions for a *partially* customizable village mod

So, I want to try my hand at a partially customizable village mod. It isn't hard, enable, prid and disable aren't hard. So, yeah. You wouldn't have a massive county, but you would have a nice town with named people and random, unnamed people moving in, with the occassional invasion, depending on where your village is - near Skyrim? FUCK YOU, say the fearsome Sabertooth bandit clans. Near Morrowind? Have fun fighting against against the Telvanni! There would be 2 locations for every county (I.E Leyawiin area, Skingrad area) in which you can build your village. This would amount to roughly 18 villages I'd need to make. You'd choose your village type - military (smithies, guard tower, keeps, castles AHOY, but it wouldn't yield much money, although obviously you'd have your own little personal army at hand.), ecclesiastic, religious - various churches, medium income, can base your church to exactly one god, and fanatic hordes at your hand. Agricultural - farms, markets and the like, high upkeep but only an unorganized and weak militia would stand as defense. The building locations would be pre-done. You would own only one village. The village would be able to grow into a town, and then a small city, but no more, the Elder Council doesn't want anymore troublesome counts. So, any suggestions, ideas?
