For a long time I've been interested in something that ought to be possible if you can change leaders based on time (i.e. RFC): changing leaders' appearance based on religion. If Huayna Capac is Christian, he doesn't have suns on him, he has crucifixes. If Isabella is Jewish, she doesn't have crosses, she has Stars of David. Ditto for Charlemagne. It would only apply for obvious religious symbols, though, but it could also be possible to have "hidden" leaders where they look like versions of normal leaders, but in their religion's dress code (i.e. Elizabeth wouldn't show her hair if she were Muslim)
Also, is it possible to go back to the CIII thing where the leader appearance changes based on time in the game? i.e. they look ancient during the Ancient and Classical Eras, Medieval during the Medieval and Renaissance Eras, Industrial During the Industrial Era, Modern during the Modern Era, and Futuristic during the Future Era. I just thought, since it happens in RFC where you can play against Peter and he turns into Catherine who turns into Stalin, or you can play against Qin Shi Huang who turns into Ming Tai Tsu who turns into Mao Zedong, and there's no Civilopedia entry for Ming Tai Tsu, it ought to be possible.
Is this liked, or is it beyond the scope of this mod?
