Mercenary Mobs

So I have a good idea to create a kinda neutral, but powerful mob I call it Mercenaries. They can become either hostile or friendly depending on the player decision. So in order to be neutral just stay away or don't show any weapon or force just like the piglin in some sense. However, in order for them not to attack you or stealing your personal stuff you can buy their loyalty with diamonds, food, golds, emeralds or anythings that they offer or want just like villager. From there you have effectively take control of them all the time you pays what they demand. The more things or the bigger the mobs (like Raids and other stuff) the higher the prices. You can effectively also make them work in construction (mostly superficial diggins). However, if they don't get payed they will revolt if the contract is broken. In addition, they can also be bougth by other mobs or players.
