Loot tower

I would like to see the loot tower be added to minecraft as a stucture , so the loot tower is simply a tower in mountains that reaches the sky and has 5 block high floors and has random loot from the overworld , the higher the person gets the better the loot gets so it might be a 3 or 5 or randomly generated number of floors and it might not be in mountains it might be in biomes in different looks so in desert its made from sandstone and other places its made of stone bricks and contains uncraftable banner designs so it generates 40% of the time so its a kind of rare structure
