Pokeball / Mob Capture

Please create an item that allows you to capture and transport mobs. I'm building a monster museum and it is a pain to transport some mobs. For example, it would take me days to transport a Shulker from The End to the overworld using pistons, so I'm not going to do it. I know this would be a powerful feature so the item should require rare crafting materials / tough requirements. Maybe capturing a mob could require splashing them with a potion of weaknesses followed by clicking them with an Enderchest. Placing the captured mob would break the capture item.
