Mini Banker

Before reading, please note that this is just a silly idea that I had. Don't expect something awesome.

A mini banker which is a totem of undying or something like that (point is, it looks like a villager) and can have an alterable price! It can be crouch+right-clicked to absorb emeralds, and that acts like a toggle (turns it off too). It is a compact emerald storage in your inventory. The only issue with it (from a technical point of view) is it picking up emeralds with a full inventory...
Another even sillier idea building on the previous one is that it has a function like horses! You can combine them together and get chances of creating better or worse ones. The better it is, the more emeralds it can store!

 

This is almost the same suggestion as this.

Except for the second part (sorta).

 

Sorry; I just spit this little thing into suggestions. Didn't read other threads if it has been said before.

 

hey look it's my suggestion

Didn't think of "breeding" these like horses, that's interesting :D
