Zz'Rot Portal game mode?

So I recently discovered the Zz'rot portal. That item is hilarious and I think it could be the focus of a new game mode. Perhaps something along the lines of URF but only with that item ie, each player can have 6 portals active (1 per item) and they shoot out voidlings at a rate of 1/sec or more. Give them different abilities. I don't know, it could be fun.
