New villager job

What if we have a new job- the Healer- for villagers? The Healer's job block could be a beacon (beacons can give regeneration). They trade potions of healing, potions of regeneration, glistening melon slices, ghast tears, enchanted golden apples, golde apples finally(really rare), and more beacons for rich things like emeralds, diamonds, gold ingots, more. Can cure hurt villagers, zombie villagers, and rarely repair iron golems.

We could also have the Builder, who  can build new houses for villagers; job block: crafting table. Give emeralds and building materials (iron ingots count) for MORE building materials (different of course).
