Nether upgrade with lava

Imagine a potion of lava sight! So you can see in lava! With fire resistand and lava sight you could go under and maybe a few mobs in the lava! These mobs can be tricky to kill even with netherite! They could drop a scale or something like that. Make sure it won’t burn! These can be collected to make a better than netherite tools and armour. With a helmet equipped of this scale or whatever we can see and breath underwater without potions. Obviously this will be changed but something like that would be cool.
