It would be nice customize and enhance the villagers with curios items.

Example: Accessories, like some hats, collars, animal ears... from other mods with good models that are restricted to curios, and cannot be put in armor slots. This compatibility change may let the villagers put on the curio accessory, and would be visible if possible.

It would also make them more close to the player, and would give immersion and roleplay capabilities.
