Other variants of blaze

My idea is if we already got the blaze and the breeze why we don't have a variant of earth and another variant of water.

first the variant of earth my idea is that this work like a hostile mob, but he got the function of move faster the other mobs and maybe send them to you, but he can't attack directly.

and the variant of water, my idea is to improve the conduit make it a mob that stay in a zone of blocs placed by the player, and this could be an opportunity to upgrade the ocean whit new biomes and mobs like the skeleton of the water and adding the idea of a lost civilization whit a village under water, and making easier to get the trident or more like the mace that you know that you can get it in a place and whit a challenge.
