Problem is that Pygmies and Capoids are not extremely far genetically from the rest of the Africans. That’s the major problem as I see it. I am wondering if there is some distance on some charts though.
My main question at the moment is can you go ahead and expand the 4 major races to 6 by including Capoids, Congoids (I think that is better than “Africans”) and Pygmies??!!!
Africans, Caucasians, Asians and Oceanians (Papuans and Aborigines) are the four major races.
One thing you might be able to do is split the Horners. They are indeed about halfway between Africans and Arab/North African Caucasoids.
You could also split off the South Indians. They are about halfway between Caucasoids and Asians on some charts.
