You're assuming that the reproductive process that would take place after such and event with a smaller group of humans would be as it is now, natural. With the genetic technology we have available now we could create very genetically diverse embryos for womb implantation, and the interbreeding problem would be solved. In such a scenerio, "eugenics" would no longer be a dirty word, as survival of the human species would depend on it.
