Hm, well first of all the number keys are already in use so it would probably more be like /spawn tori/uke <value> <x,y,z> or /opt 3rd/4th tori/uke 1/0 ect. Although Iirc the current physics engine used in toribash can't handle more than two characters. I don't know how true this statement is though, because a tori is just mathematical objects(Citation needed), and as we all know, mod makers can add more objects into the game via mods. I think that it would be possible to add more toris, but would it really be worth it? Also to back up my statement with saying it would be possible, take the freecam for example, that adds a 3rd tori into the game that is used as a camera(Citation needed), this is why if you hit 2 on your keyboard you can notice the fps drop slightly.
