Its already enough work for them to currently put each spell that comes out on every new and different item, i dont think they need more pressure and more work as it is.
So i dont think this option would ever come out.
I don't think this is a good idea as it would be even more work to be put into each spell and it would require extra coding to be done to make it possible. I think if the staff intended the nametags to be spell-able, they would have released them as such. Not trying to be negative, but as much as this might be nice to go with the avies, I think there are more disadvantages than advantages here. omo
I think maybe they could in the future sell standalone recolours of the nametags as that would probably be a more viable option. ouo
