You do know this won't really change much right? Unless you somehow missed many fan site discussions on why people choose miqo'te (and or other female characters) they will stay female miqo'te. (and if/when they add these alternate genders, there will be a ton more miqo'te running around both male and female)
Most people I've seen through fan site discussions go male hyuran/elzen because "there is no male miqo'te" and did "not want to play a female character".
I will repeat what many other fan site discussions on the topic as usual say. "Female miqo'te will be chosen mostly because some guys rather see a female on their screen then a male". For some people they play the game for enjoyment and they don't enjoy staring at a guy all the time playing, but a female instead. :P
