An Addition to the Copper Horse Armor

I was very excited to see the addition of copper horse armor in the game. though, I was disappointed when I heard that it was not craftable, especially since other horse armor types had recently been made craftable.

I have a suggestion that I think could improve the game, and I would appreciate your consideration.
The copper horse armor would be made craftable, and weathered versions would be added only obtainable via structures. The more weathered they are, the rarer they would get. 

For example:
Copper Horse Armor (craftable)
Exposed Copper Horse Armor (found in desert temples with a 15% chance to spawn)
Weathered Copper Horse Armor (found in trail ruins with a 10% chance to spawn)
Oxidized Copper Horse Armor (found in jungle temples with a 5% chance to spawn)

They would all probably have the same stats, and would encourage the player to explore more, bringing more customization, and adding new uses to these structures.
