When on fire while wearing a carved pumpkin, it turns into a jack 'o lantern

Wearable pumpkins are fun. Vut there are two varieties of the carved pumpkin, and I want to present this idea. It goes as follows: If a player or mob is currently on fire (they walked into lava or got affected by fire aspect, etc.) Then the carved pumkin on their head will visually change into a jack'o lanter for the duration of the burn. I suggest that it be a visual change, because if you could walk and create light, the game would have to change so that all entities on fire generate light. [Fps]
