sculk zombies and skeletons?

straight forward when a zombie or skeleton spawns on sculk or stays on it for to long they turn into their sculk variants if you get hit by one you get blindness and poison and nausea and why the hell not add creepers to the mix where when they explode they spread sculk and sculk pores which are kinda like lingering potions and when stepped in you get poison and slowness i thought of all of this on the spot so dont tear me apart please
