Ancient Altar ( Player Heads in Bedrock, and in survival )

Player heads obtainable in Bedrock edition and in survival mode. This could be obtained from a new ancient altar that could appear either super deep in one of the new cave biomes, or in a new temple found somewhere in Minecraft. Using a totem of Undying on this altar would allow you to select either yourself, or another player in the game to create a skull of. Maybe to make it even harder to obtain, you'd have to use a skeleton skull or something as well.
