Dear Square Enix, can you remove the race restrictions on hairstyles?

I'm sure changing the XYZ coordinates for the in-game hairstyle models to fit that races' head shape/size isn't much of an issue, seeing as how the Lightning hair looks on AuRa females.

The problem isn't that it is difficult. The problem is that it takes game resources that may not be available to lower end systems (like the PS3).
Loading 50 hairstyles in 1 zone is a thing. Loading 300 hairstyles due to different race/gender configurations however is different and lag will occur from client side. Lag may even occur from server side too at that point.
It's the same thing about character details. It's not difficult to implement. The challenge is shrinking the resources it uses. You gotta ditch certain things so the game isn't unplayable on PS3.
