New bosses for Minecraft

Hi minecraft, can you add a feature with update bosses like the wither so if we want the wither we can't spawn it but it spawns itself somewhere or maybe in the nether at the soul sand valley and also make the ancient city guardian (the warden) spawn only one? Because I feel like the wardens spawn too much and also a cool down after the warden dies? And also can you make the warden drop something useful as the ancient city guardian? Like materials to build a new weapon or something or maybe something ancient in a new update? And maybe add a new dimension connected to the ancient city? And also can you add a boss health bar on the warden so we can see better? And can you add something like mobs raiding our base or house? Because it will be challenging and interesting and also can you make the village can get raided with a chance of percentage because always having to drink ominous bottles aren't that cool and can you add the Herobrine? Because I really want to see Herobrine but at a specific night? And at that night he will know where we are and we have to kill him or it will never be day time and also when we fight Herobrine there are no mobs like zombies and more and also give Herobrine a boss health bar and good drops. And next one is the ender eye because why can we defeat the game so easily? Minecraft is about adventure and it wouldn't be great if the ender eye only needs an ender pearl + a blaze powder so can you make the crafting recipe harder so it will be more fun?
