Of course!!!

In order to make a wide variety of villagers any "head" can be attached to any "body". This means the color hue of the head has has to be the same color of the body to make it realistic or it would be awkward.

We could have separate grids for a different skin color where the heads would attach to the bodies of this grid.

What if I want, then, to breed a villager from the first grid to a villager from the second grid... from which grid would the child be taken from?
