The lava caves biome in the over world

Yes I know what your thinking. This sounds just like the nether. This is just gana be a biome in the over world that is JUST LIKE THE NETHER. Its gana be something that is already another world in Minecraft. But no it's not. I feel like we need to give the over world some more lava, so the nether is not the only world to be known for it in Minecraft. I feel like we need a nether ish biome in the over world, not to nether like but just with a lot of lava in it. This biome would be called the lava caves. This biome would introduce a new type of stone called lava stone. It looks just like stone but with lava glowing cracks in it to give it more color. When the stone is cobblestone, it would be called lava cobblestone, and the cracks in the cobblestone would be lava glowing colors too. There would be normal stone colored dripstone, just the color of normal stone for plane caves and the lava caves. There would be more mobs there. too like. Lava Scorpions, and normal Scorpions just to make lava Scorpions make sense, lava zombies, that would be awesome, and thats it but it still would be cool. I feel like the lava caves would be a fun new cave biome for the over world, and giving the over world some more nether like stuff.
