An idea about the Villager Rebalancing (Use llamas)

My only issue I have is getting your librarians from one village to your base for enchants.  I understand and respect the reasons for the rebalance.  

My Suggestion is since llamas can crate a " Caravan " why not allow tamed only llamas transport villagers and form a " Caravan " that follows the player to the base?   This could help with the transporting villagers around.  Would force the player to make small bridges, and also add a little bit of risk having to travel a minecraft day to their base.
