Friendly Creaking Heart

So, how about if you obtain a creaking heart block and do something with it, you could make the heart friendly, so it wont spawn Creakings, but instead, it would protect you from damage. Imagine placing the heart in a fight, so it would protect you from mobs attacks. It must have a limited usage so it wont be too op. Maybe it could protect you until you reach the hearts protecting limit, and the heart would turn off, so you need to recharge it somehow.
