Traveling villager Selling exclusive item (Armor mold)

It would be interesting if they added an exclusive sale for the nomadic villager, like a different armor mold, because theoretically he travels to various places selling items he finds, so...He would need something that required a lot of walking and exploring to obtain; the design could be related to something characteristic of the Villager, like a llama or another design, as this would attract attention and be more interesting. For people to search for this Villager and become more eager for its appearance.
