If there are 1% of the playerbase or potential new players who would ever consider playing a beast-like Femhroth, but 25% who would consider a more Miqote-like Femhroth, you would technically serve more players with the second option. You would essentially offer more customization for female Miqote players by allowing them to also play a taller, green or pink-skinned catgirl with a bunch of alternate customization options.
Even if you consider players who would only like beastly Femhroth and don't care about anything else, I think those players would be such an extreme minority that they would be easily eclipsed by even those who would only play Miqohroth.
Don't expect beastly Femhroths is what I say! Be pleasently surprised if u get them, but don't be disappointed if they are big Miqos.
