New biome idea

Hello! I have an idea I hope you guys will see. So, I was thinking that it would be cool if you guys added another snow biome, with like frozen trees and the planks and wood would be blueish. And, villages would be made out of that wood in that biome. And, it would be kinda rare to see the biome, but there would be 2x as much of those snow houses with the zombie villagers. (I forgot the name of them lol) and in caves there, there would be a couple of new mobs. It would have snow mites, and when they bite you they start to give you frostbite, and they melt when near fire or lava, and there would be the frozen endermen, they would carry snow around and of course, you cannot look at them or they will attack, they would attack by throwing snowballs at you, in which they freeze you, I also have one last mob which would be the frozen witch. It would throw new rotations added the slow you don’t a freeze you, and it would throw poison, and withering potions at you. When you kill these mobs, they will drop xp, snow potions, and the surrounding area would turn into snow. The biome would be called the frigid biome. Thank you for reading my message, and have a good day!
