They could at least extend the new human hair styles to the other races that use "human" hair. Silly that even cyborgs can't access them.
Lekku wraps/decorations would be nice too.
I think a large reason why we see so many humans on the fleet is specifically because of the "new" hairstyles. If those hairstyles were unlocked for the other races that were applicable, we would see a return to the diversity that we had prior to them. More options are always good.
