A fairly small suggestion: Make spawner eggs for different villagers, such as Spawn Priest, Spawn Butcher, Spawn Blacksmith, etc.
Even with Single Player Commands I don't know how to spawn the villager types, and with spawner eggs you could precisely spawn them wherever you like, whenever you like.
