So, I was looking for a way to make Anthros the only race to exist.

What I discovered was the mod: Xenotype Spawn Control .
But I had to make each slider (15 total) balanced with EVERY faction.

Then, I realized that if you make ONE xenotype with EVERY head (you can throw every skin color to if you want), and for safety, make them bald and beardless... and bam!
Now that xenotype has the properties that
A: it will be a random head each time
B: it is only one race so it is way easier to work with that other mod, just crank that xenotype to 100% and you are done!
(C: if you added the colors, then you get random colors too).

So now it mimics the Anthro Race Mod way better.
Here is a picture to better describe what I did

Hopefully this information helps someone else not spend 2 hours looking up mods that work better (spoiler, there is none)
