Datapack for a skinning system ?

So we all know the good old MMO skinning system when you slay a wolf or a cow and you skin it for its leather or wolf pelt. And then get a chance to get an additional drop from this.
I was wondering if its possible to make a datapack that can do this, and then use the emotes from essentials mod to trigger a custom animation. That makes it look like you are skinning the mob ?
This is kinda a make and break idea of mine, i know 0 about datapack making. But if this is possible, i would be willing to dig my nose even further down the drain to learn!
*Reason for datapack, is simply so a person would only have to download a custom resourcepack and not download custom mods. And then as a optional mod, have essentials for the animations 🙂 *
