Transform the Villager Experience

This is my dream for Minecraft...

3 new villagers....#1 A Miner.....#2 A builder.....#3 A Warrior

#1 The Miner does what his name says. He mines and collects all resources (even wood) for the village. His skill in this is based on his level. Higher level (you level him up) the more and better resources he finds.

#2 The Builder does what his name says, he builds things, all things. He builds houses for the villagers, he builds structures to beautify the village, builds paths, bridges, ect. Higher his level, the higher level tech the village has.

#3 The Warrior does what his name says. He fights, he protects the village from enemies. From mobs to players who are aggressive. His skill is also based on his level. He can also get armor and weapons from the armorer & toolsmith. 

This would completely transform all villages as the player becomes God and levels up these villagers with a purpose. To see what they can build. From castle walls, large buildings, to everything else. This also would include enhancing the others. Like farmers who build better larger farms. Armorers who outfit the villagers. All villagers working together, storing their supplies in chests in the warehouses they build or in their houses. 

Anyway, probably a pipedream and massively complicated. Most players could care less about the village but I would love to see this idea come to life one day. 

Thank you
