1. There already are some (semi-)anime characters.
2. Holotech can't just create any (anime) character they want for one simple reason: copyright. The need permission from the copyright-holder of the (anime-)character to be allowed to create them. The community however does not have this restriction and could in theory create any anime avatar and rig it up for FaceRig.
For some example of what users already made, take a look at the workshop:

Also, speaking about anime characters:
