I'd love to to see an ability to create base characters that we could then choose as "Parents", select the number of offspring, how many grand children, etc. Then the "Genetics" algorithm will automatically create the children, and grand children, etc. all based on the Prime Pair (Or whatever number of parents) of parents characteristics: cheek height/weight, body build, eye color, hair color, etc..

With procedural builds and an ability to choose the number of offspring, it would be easy to create villages of believable family units. Cousins who live nearby, or whole broods of this or that creature. Then small studio's or one person creators can create many character assets to populate their world without spending years to do it.
