I dont know if this has been done, or someone is working on it, but it would be a very great mod! I also guess it is a huge amount of work... In civ3 the leaderheads adjusted their appearance to the era your civ was in, so even a "modern" leader would we dressed in medieval clothes in the medieval era, and vice versa. Does this exist as a mod for de civ 4 leaderheads? That would be great! (making it would be muck work, because you have to adjust all the leaderheads in the game, and script it so that they change correctly...)
