I know this may not be for everyone but I know my self and some other players would like to be able to access the female hairs / animations like sitting with male characters.
I hope one day we'll get it. but in all honesty with how SE let personal bias get in the way of the bunny suit I kind of doubt it.
It's be possible, just a lot of skeletons to rework. If they did do it, it'd be like a few at a time or so. Some are probably easier than others like giving female Miqo'te access to the male joy emote, since they can essentially already do, but who wants to drink some orange juice whenever they want to wiggle their ears?
Sadly how miqote are made is there hair and ears are apart of the same mesh so to give them more options they would have to make more ears to fit the hair
They could do it just alot of work
I'm still waiting for a "Reverse" option similar to what we currently have for face paints.
