Changing item texture using NBT data

I suggest adding a way to make item have multiple textures and every texture have it's own condtions for example if item durability is low it will have a texture that looks like it's broken, if NBT data tag "test" is true it will have anothet texture, this idea helps because instead of making another item for every state we can make one item will multiple textures and also using same conditions we can give the item multiple functions!
