Making the Wandering Trader useful

My idea is simple and it’s to make the wandering trader useful by making him sell to the player useful and unique items they desire like the enchanted golden apple or even the new mace core or even enchanted books that you can’t obtain as a player from the enchanted table but I want it to be at higher cost like 50 or even a 64 of emeralds I think this change will finally make the wandering trader useful and not only a way to get lead from the lamas of his.
