From what I have heard, there are programs that can allow players to create their own civilization. Undertaking this process is almost as if you are trying to create a new game from scratch, so yes it can be done but the method to do that can be very complex. In that case, I would ask users like Izalith and Nick3069 who happen to be more familiar with mods than I am.
