Villagers drop their character item and a new animal mob idea

What if when zombie villagers die they drop their “character trait” item. Example: farmer drops hat. When player picks up the hat they gain that skill. I.e. collecting the farmers hat allows the player to grow crops twice as fast and harvest a larger crop gathering. As a blacksmith making/enchanting items costs less enchantment so on and so forth. Also, as an added animal mob a gorilla would be cool in the jungle.
