Ideas for Snowdown event

Ok, i was playin some aram and i had an awesome idea for a summoners rift map for Snowdown, it started with just adding snowball but instead of a cooldown timer its how far you move like your building up snow. a poro king, though out of place maybe something else would be better, that goes down mid and two poro "knights" that go down the side lanes. Then, it went on to the bushes should be turned into snow piles just for funzies. But the big thing i thought of would be since its cold and snowing, wouldn't the river freeze over? Like have champions slide around, so when you start in a direction you keep going that way at a declining speed unless you keep clicking that way you build speed, or like the whole jungle is frozen. Just make everything insane. everyone should post some ideas and maybe riot will take a few.
