Maybe someone found this out a long time ago when there were discussions about good civilization combinations:
My ally tributed me an armored car and I was France. When the AC died a conscript popped out!
Russia and France could work together with the armored cars. The bonus of healing and the conscript popping out seems to make this a good idea, and houses could be great to go with it.
France and Russia are the "best" civs already, or considered the only ones worth playing by many good players. And they can work together well as a team... so is there really any reason to play as a different civ combo? In a game of equal teams, can Russia and France be defeated? I say no.
