Request to add dimensions village, or underground village

My idea for the villages:

IN the nether, it could give blaze rods, blocks, armor, gold, maybe some new nether ore (?) and even ancient debris. There could be maps to nether fortresses or bastions in trading/chests.

In the end, the villagers would look more like endermens but still remain at least partially human. Again, they could trade maps to new structures (?) or the end cities, the chest would have their armor and enderpearls, also food. maybe add something like enderite ykyk. 

Underground villages would be fairly the same in the trade aspect compared to noraml villages yet very different in the building. instead of houses, it would be like rooms and tunnels that relate the different rooms together, each profession would have its own room and loot chests.

Overall i think this is a great idea! :D
