How to give 3D models to vanilla armors? [1.12.2]

[Leggerrr]

Sort of new to modding, but I know how to make basic armor and even armor with actual models. How does one go about giving 3D models to the basic vanilla armors (Leather, Iron, Gold and Diamond)? I know there's probably some round about ways, but I figured there's simpler ways as well.

You can replace vanilla armor with your own custom armor that is identical to vanilla armor except for the 3D texture.

That's what I was thinking. Essentially make the recipes craft this new armor instead. I didn't know if there was any easier alternative methods, but I guess I'll do this instead.

That won't remove them from the game entirely instead override their registry entry. By registering an Item with the same registry name.

I knew it wouldn't totally remove the original armor from the game, as it would still always be there in creative. How would you go about overriding their registry entry?
