Can you also make the mc have other sub bendings like combustion bending, lava bending (technically earth bending sub type but you know it have fire in it), spirit bending (again water bending but instead of water you use the negative and positive chi to change the nature. Maybe make it a chi control technique),and other things like Scorch style from naruto, different fire from doupo, and trying to make lightning a main bending not just sub skill by mc being able to generate lightning himself (without changing chi nature) and making black lightning etc..
