I got a cool idea, but not the modding skills required to make this a mod myself. I am hoping someone will take this idea and turn it into a mod (hopefully someday Paradox might even turn it into game content). The Human Revolution mod adds a new set of more futuristic looking human portraits/clothes. What I want is a mod that adds a feature where Humans look like the vanilla version in the Early game, but when enough time and research has based, they turn into looking like the HR version Humans in the Late game. Maybe just one tech, or maybe several ones. For example when Advanced Governments, Terraforming and Cloning has been researched. I was inspired by the Early Western and Eastern, and High/Late Western and Eastern unit models from CK2. It would be appropriately sci-fi to have the great advancement in technology reflected in the population and characters. Early Humans would look similar to us, but Late Humans would look more advanced, "ascended" or Fallen-like. Obviously, this needs to be optional.
