Snowman Faces!!

Could you add different snowman faces? I think it would be really fun. I'm also assuming that I'm not the only one who thought of this. But I think it would be really cool if we could! I know it doesn't have a purpose but I think there should be 11 faces in total (including the regular snowman face.)! I also had another idea that you can get an achievement for getting all of the faces, and if you get the achievement you can unlock a new outfit/mask that is a snowman face/body.
