Villager castle and peaceful pillagers pls read my idea

My idea is a villager castle in vanilla or add on minecraft and inside are villager guards or iron golems and theee should be a villager king with a crwon and red clothes thats very pretected. When killing the king villager he drops a item and when you habe the item then pillagers wont be hostile to you only if you attack them first. Also you can find maps of where the villager castle location is in outposts or mansion and there should be good loot in the castle. Its kinda like the overworld version of the bastion
