Sculk variants of zombies

As far as we know, there aren't any Deep Dark biome-specific mobs other than the Warden, which, depending on how many wardens there are in the Deep Dark caves, might be a problem. So what if there was a Sculk-type zombie, or maybe a Sculk skeleton, which spawned in the Deep Dark and looked like smaller, zombie-sized wardens that could communicate with the Warden and the sculk sensors? It would kind of ruin it if there were all these cool new additions for the deep dark, as well as the generic old mobs, but also be a little boring if the only mobs were the Wardens.
