So, why isn't this a thing yet?

Because the Japanese society is extremely judgemental of anything that relate to children. When the hentai friends get wind of this and rush to play the game making doujins about these loli'tes, you can be sure Square Enix will be under pressure to stop designing these.

A small company of nobody can afford to do it and stand up straight, claiming gentleman. Square Enix cannot.

yes they are, but thinking adding/having a certain type of anything(whatever that pic is, cant see it) is going to promote people to make doujins is pretty stupid. it hasnt stopped people from making doujins about Mashiro(Mikakunin de Shinkōkei)or Yotsuba(Yotsubato).(off topic, i want more Suwakoto. Suwako as Yotsuba is great.) rule 34 exists for a reason, not a good one but its there. case in point; there are doujins of this game from 2 years ago.
the main reason i see any company not having kids/children do fighting is because it would somehow support violence in children. And everyone knows, you cant have children fight in games.
