Heart Shaped Firework with Cherry Leaves

I think it would be really cute if we could have fireworks shaped like hearts! 

If a Firework Star is made with a Cherry Leaf Block, it should explode in a heart shape, similar to the heart shape of cherry blossom petals. It would also give another use to Cherry Leaves and another reason to travel to the Cherry Grove. Cherry Leaves would also fit in with the rarity of other materials needed for firework shapes, those being Gold Nuggets, Feathers, Fire Charges, and Heads.
