I'm definitely game if you're still looking for someone. As far as "realistic but different" goes, I've been toying around lately with an idea for an alt-historical setting where men decided in the late 1940s that all women's suffrage had brought was a depression and a global war, and so repealed the 19th amendment and reduced women to near chattel slavery. Lots of ordinary settings are livened up, I think, by the idea that the men are taking out their frustrations on the women they see as having destroyed the world, but certain specific settings offer their own unique twists (like the "liberation" of the Japanese internment camps). Let me know if it piques your interest.
