Female Hrothgar and Male Viera

Personally I think letting them wear hats should be the first priority

Eh, I'd rather have access to the playable races in full. That's far more glaring than not being able to use most headgear - especially when the lack of hats is very much in line with the flaws other race/gender combinations already deal with such as highlander men not having access to eyebrows.
