The Sculk Dimension

There has been a lot of myths about opening a portal in the rare Ancient City, added in 1.19, including the massive ring in the center of the structure made of Reinforced Deepslate. I would imagine the way to open the portal would be to put 4 Heavy Cores in the corners of the ring. When the portal is activated, you can go inside, and see what the Deep Dark looked like, before the Sculk infestation. There would be villagers, houses, and most importantly, The Warden. It wouldn't be covered in sculk, but instead would look almost like an Iron Golem. It would probably be boney, and have 3 axolotls, on it's shoulders and on it's head. There would also be a custom variant of the villager for the biome, like maybe with leather clothes that come from the bat?
