Gamemode idea or something I don't really know

It's a small arena, in a square, and it's done in a tournament style. Eight people. One v one in this small arena, where all the spells are on a very small cooldown, and everyone is level 18, with a selected amount of gold to start out with in the big inning. After bans and choosing (4 random people ban) people choose champ and buy items. Then, the one v one arena starts in a tournament bracket format. The loser of the first match goes into the loser bracket, who compete to see who will fight the winners bracket winner, and win the game. All of the matches are fast paced, and short, due to the small space. Determining on which place you got, you get certain amounts of ip. A winner could even get a special icon. Second place would get a not as cool icon. I hope you liked my idea that will never be made into a gamemode.
