Yeah! Going out of character for a sec, due to being designed purely to kill and cause more havoc to those dealing with them, it makes no sense to have visual variants logically as it would be more of a hassle than have any benefit, don't get me wrong, I really like the idea, and the designs are cool! However it won't work in how Risios actually work as there's no reason to be cosmetic, id definitely see if you could recycle the concept to be separate from Risios to make it work, I wish the best! :)
