Hexakill urf Howling Abyss

Not as a "BRING BACK URF NOW RIOT PLS" topic, but how much fun would a hexakill urf howling abyss gamemode be? I think it would be hilarious. Everyone cramped into a tiny lane spamming abilities as fast as they can. I guess Sona would have to go, and probably Kassadin, along with a few others, but what do you guys think?
