Elemetal shards and armour

there would be fire, water, lightning and earth shards. fire and lightning shards can be obtained by killing magma cubes. you can get water shards by killing guardians and earth shards can be obtained in a sand temple. all of these can be crafted into armour, the crafting recipe is the same as other armour, and finally these armours are better than diamond but worse than netherite. i hope you like my idea :)
