Well my view of this mod would be it would have no racial traits at all, but since I am not doing the mod anyway feel free to suggest it.
I think those things you mentioned would be neat to have as tech areas. General empire advancment stuff that would allow beter cities, and thus better production and reproduction. But since they are all one race, humans, it wouldn't be something someone else couldn't also develop themselves given the time and research.
