Personal Skeleton Guards with crafting from Bone Blocks

If a player finds a Fossil in the Overworld, or if they go to the Soul Sand Valley Biome, they can mine at least 6 Bone Blocks of Fossil or Nether Fossil so they could use the Bone Blocks to make their very own personal skeleton guard. The crafting recipe could be in the shape of a stick figure worth of Bone Blocks. The end result could be a standard Skeleton Egg that you could place anywhere. It could have two main commands: "stay" or "follow". A Skeleton Guard would have the same bow and arrows as any other skeleton, but it could have a leather chestplate that you could dye different colors like the collars of tamed wolves. It will not despawn, nor attack you if you hit it. You would heal it with bonemeal. I think that this would be a fun addition to Minecraft as not only is it adding a helpful skeleton ally for fighting with you, but it will make the Soul Sand Valley a valuable place to go if players so desire!
