Okay. That's something I've given some thought to. The northern Berbers are very Caucasian, but the southern Berbers, the Tuareg, are much darker. So it's not an easy call. Unfortunately, color is not an RGB value, so it makes historically more biologically diverse populations like the Andalusi and Berbers more difficult to portray.
At the moment, I think that it runs alongside my mod perfectly (it did this morning), but I think that it would be something that I would like to integrate into Project Rodrigo at some point, with your permission of course. I have adjusted the cultures file to include Sephardi Jews, Gypsies (Romani), and Malians, though I haven't finalized what they'll look like.
