Iron Golem upgrade

Since we can repair Iron Golems with an Iron Ingot, I thought it may be cool, if they could get a little power effect when you repair them with a whole Iron Block/Enchanted Ingot/Block. It could be useful when playing Raids that you underestimated, or when you just need a stronger support in any fights. Maybe it could be like players take potions that the Golem gets increased strength and resistance for a short period of time, and also a visual update, making them look like fancy energy is flowing through them. It's not insanely useful, but it would give them more interaction and character.
