Why don't you do one based on it, then release some remakes of the actual charas as freebies. Like this: Do one based on it, black and white, so people can change the colours, and also with different models for a variaty. Then, do some textures that ae copies of the actual charas, and post them as freebies. Or you could just make the Eva expansion a whole freebie in itself...then there are no copywright infringments if Asuka/Rei/Shinji/That other guy/Kawarou's textures are included. Oh, and just another idea for a product. How about a towel...a morphable towel with creases that can be wrapped around the body and be pulled in various places, excellent for bath scenes. And a bonus towel for long hair (the 'turban' towel). Just an idea.
