Zombie Villager changes

Zombie Villagers have been a feature for a long time in Minecraft, but this suggestion is to give them more variety and differentiate them from regular zombies, by making their attacking patterns different from ordinary zombies. For example, a zombie villager fisherman will spawn with a fishing rod and try to pull you in so it can attack, or a fletcher using its archery skills to fight at a range. To add more, maybe certain zombie villagers play a supporting role to other monsters, like the armorer being able to equip zombies and skeletons with extra gear, or the weaponsmith villager being able to equip monsters with new weapons. While there would be a good amount of stuff to be aware about, I believe these changes would add a lot to the behavior of zombie villagers and bring new challenges as a player when fighting hoards of enemies.
