There is a mod called Faction Blender that adds two amalgam colonies to the game, which have a population built up from all of the modded races you have installed. One of the colonies is friendly, the other is hostile.

There is also another mod called Pawnkind Race Diversification (Continued) that gives you the ability to change the chance that different races spawn in. I was playing a game where regular humans were actually quite rare.
