I would enjoy new options from a wider range of body types (personally I actually want huger boobs/hips/butt), to different faces, tattoos, horn types and even ears. I'd love if I could have longer ears. Really I think PSO 2 has some of the best char customization because you can even move your accessories around. What might normally could be a generic headband could be combined with other parts to make a one of a kind hat.

Being realistic, I don't think they will do much. I think that not only are textures the problem, but I think the base game can't handle it.

Thinking more about it, I think the base game itself might be the cause of a lot of woes for the game in general.
