More variety in thegame

Dear Microsoft/Mojang. I have some Ideas hat I think would be great for the game and make it more dreamy and fantasy like.
First of all: The stone golem. People have wanted more golems for a while that can defend you, and the already existing golems add some variety but this one does great. The stone golem s at half the player's height and has 20 hearts. This mob is a cube, with a smaller cube on the bottom where its legs come out of, it has the thing where the face is on the torso, it has holes on its arms that can be used to shoot out potions and arrows.
The overworld has the villager for trading, the nether has the piglins, but the end? I think it should have the lurker: a mob at twice the players height and has some iron on its body. It trades food and defensive items for iron such as: 5 iron for an enderpearl, 2 iron for 7 bread, and a chestplate for 7 pearls. This mob has something that looks like the shulker.
We need an endercreeper! People have talked about an ender-creeper but heres my idea. This mob can teleport like an enderman and explode like a creeper, but when killed it drops an item that can be crafted with endstone to make C&E, which is just throwable tnt.
Here's an Idea I dont see anyone talk about: the ender-cube. This mob can be killed like the regular slime and magma cube, but it drops a sticky pearl, when thrown it makes a big bud of slime, like the ice pearls in education addition.
