Mountain cave mini dungeons

So, I was thinking, why not add the redstone golem from mc dungeons (not the redstone mostruosity, the golem, the smaller one, becouse I think that the mostruosity is a little too much for vanilla Minecraft), but how can it fit in Minecraft? Well, we see in the mc dungeons trailer that the arch illager finds these statues in a mountain, so why not add a new structure to the mountains? Not a surface structure, but more like a mob spawner dungeon, a chamber/room that generates in ceves, but only mountain biome caves, so it generates inside mountains but, for example above y 80/100, so that to find it you have to search specifically in caves inside mountains. I was also thinking how that dungeon can be, so I think this dungeon should be made out of deepslate (variants, like bricks, etc..) so that it's a little more harder to escape since the deepslate takes more to mine than stone variants, and with a lava atmosphere, so that the lava lights the new "mini" dungeon and makes that the main enemy is the golem. The golem isn't always alive but is at first a statue, and with the presence of the player the statue activates, becoming alive. Idk what it can drop, but I know that Is a good way to implement a really well made mob into minecraft, and it can be smaller than from mc dungeons, it can be just 4 blocks wide. Please Mojang I would really love something like that, and I think I'm not the only one.
