Mossy mountains

Hello!
I have an idea for new mountain biome (warm biome)! This biome would be named Mossy mountains, they would be like normal snowy mountains, but instead of snow, we could have moss! there could also be some more mossy blocks, like mossy cobblestone and new block mossy stone, they would be pretty lush, you could see a lot of spruce and oak trees, sometimes maybe azalea!
