I don't think certain customization should have to be paid for. It is a game feature that is in need of implementation due to the way you can lose your champion in scrambles. I think at the very least we need to be able to change skin tone. This directly effects game play so they need to do something. Give a option of 10 skin tones ( wide range) and then sell packs of like 5 tones for $.99 .
As for it seeming to be high demand and a hot topic. If they made it $.99 to change your gender or for certain color packs , since it is such a desirable feature in the game I could see them making a few thousand dollars easily this way. I'd only support this if they see how popular it is by this tactic and introduce it in the next game right off the bat as a feature you bought with your game.
With respect to another weapon class just for females. It seems like a really good idea but I could also see future arguments for them being either over/under powered. If you did or didn't pay for the gender it would still cause someone gripping. Chain blades are super awesome though. They have women body builders. Just the ones that what to run around with big bulking hammers can be body builder types. Same with the guys, if you want a quicker more stealthy champion, he'd lose bulk and strength.
