New biome

The new biome is supposed to be in the Nether because although there are already a lot of details in the Nether, the lava lakes are very empty, and that's why I want a biome where lava lakes can be generated, and then I thought that biome should rarely generate but it should also you can also plant it if you do not understand how I meanSo I would then want that you have to use the pickaxe to remove a nether rack within a 20 block radius of a lava lake and then you can reveal that and a seed (I don't know how to say what the creaking heart is made of) and then it grows very slowly, the biome should be orange and there should be lava running through it like through a labyrinth
