Archeology villager

So idea is a new villager would be found in villages And it would be different from the others. Instead not buy or selling stuff for the emeralds but a bit different system something called "exchanging" for example u have a lot of the same ceramic shards and u want other veriaety u can exchange from archeology villager. Villager from exchanging and leveling him up open new better exchanges and stuff. Very little known about archeology but it would be cool to have someone to exchange to other shards you want and you need. I really like archeology it could be very cool the best exchange from archeology villager would be some kinda ancient plant seed that you can grow and that plant would be alive. The functionality would be something like cats can give u surprises like strings rotten flesh ect. The plant over time could give u meat leather feathers ect.
