Happy ghast name tag Ester egg

I had an idea inspired by existing name tag Easter eggs in Minecraft, such as naming a mob “Johnny” to change a Pillager’s behavior or “jeb_” for rainbow sheep. What if certain names could slightly alter mob behavior in a controlled and balanced way? For example, naming a Happy Ghast something like “Angry” could turn it into a hostile variant, or naming a regular Ghast “Calm” could make it passive. This wouldn’t need to be overpowered—there could be limitations, costs, or specific conditions to keep it balanced. The idea is to expand on the existing name tag Easter egg system, but in a way that adds more interaction and creativity without breaking the core gameplay.
