Sculk Zombification / Sculkification

I think if we need more hostile mobs for the caves. I'd imagine if the Sculk Growths can spread onto mobs. So for example, if a mob stays too long on any sculk growths block, then they will start getting a sort of transformation like when zombies attack villagers and they turn into zombie villagers. Like there is this... Sculk on the "sculk-ed" mob, that will make it hostile. No mater if it's a cow or a fish or a parrot, it will turn hostile. And this sculk things will grow on it's head. And the only way to free these mobs from the sculks would be by giving them some sort of item, just like curing a zombie villager with a weakness potion and a golden apple. And after a while, the mobs will turn back to normal. The only mobs that will not be affected by sculks should be the tamed animals, because they would have a strong bond with the player, so that they would fight off the sculks of their minds. The only thing that cannot be cured from this "sculkification" should be the Warden, because it looks like the entity that "IS" 100% sculk. So it cannot be cured. These "Sculk-ed" mobs would help the Wardens to know the player's location. I just think, that this needed to be added to Minecraft for a bit of spice for the upcoming "Deep Dark" biome.
