Free for all, King of the Hill, Horde Mode gametypes?

I am curious about the idea of a Free for all match that allows players to duke it out for control of a hill, and you`d gain points that would amount to a win for the match. Having a draft pick default, with a circular map that you spawn/respawn from, maybe having a single ring of bots that spawn circling the rings allowing for CS Farming, and the more you kill the harder the next wave becomes. So milking CS becomes increasingly more difficult. The minions could be void spawnlings that gradually become bigger and more deadly as you finish off waves on your way to the hill. The maximum amount of players would be 6, and a match would be over when a player hits 1000 points or something. (this is totally open to edits and the working out of kinks and whatnot, it's just an idea)

Or a Summoners Hill...? Maybe having a three-lane map with a platform in the middle that you can capture and hold in a typical 5V5. so mid lane would have a crystal that changes colour pending on which team controls it at the time. you'd also have the option to win the game traditionally by destroying the turrets and knocking out the enemies crystal.

Or a Void Horde mode... hold out in your base or protect your lanes as more and more waves of increasingly difficult waves of assorted Void Creatures swarm you and your base, seeking to destroy your crystal. Also maybe having Void Junglers doing what Junglers do, also waiting and preparing for you and your team in the jungle. So it would be very difficult and it would be a race to farm jungle creatures before Void Junglers do. (All void creatures would become unplayable except Kai`Sa and Kassidian)

These are just some ideas I`ll let others weigh in and rip this apart. Thanks! Arthur
