I dont know if this is possible, SE has shown the past years that with FFXIV, they want to avoid making cute (non gnomes type of race) males or give males feminine (Shisui outfit suprised me) clothes. There was even a interview where Yoshida said that the developers (males) do not feel comfortable with creating cute or sexy stuff for (this is also one of the many reasons why Bunny Outfit for males have been delayed for so long) male avatars. If they were to add a cute bishounen male then this would mean the male version will have a racial outfit that fits him and emotes that reflects his cuteness. I just can not see SE who has a hard time designing a cute or sexy outfit for male avatars, be able to create a bishounen male with emotes etc.

As much as I want to see cute small males (maybe like Alphinaud or Sora from Kingdom Hearts, I dont think SE will add a tall female character and small cute male. They will either make both genders the same like Lalafell or give us another Au Ra mess.
