I wouldn't mind a late-teen/early-twenties option for some of the races. Like something inbetween Alphi/Alisae and a normal height Elezen, with more youthfull face options. Could work on some races such as Hrothgar, Elezan, Roes, male Au Ra and Viera as they're pretty tall and the new option would be closer to a normal sized Hyur. For the more normal sized races and genders they could get their base options increased so it spanned more age ranges.
