League of Legends Arcade Mode Gamemode

This was an idea for an Arcade gamemode that just popped into my mind. With the release of the new Battle Boss skins that are coming out, that adds up to a total of five Boss skins (4 Battle Bosses, and Final Boss Veigar). I think it would be really fun to be able to choose one of the characters that have an Arcade skin whether you own the champ or not and use them with their Arcade skin (Sona, Hecarim, Miss Fortune, Riven, Corki, Ahri, and Ezreal). After choosing your character, you must continuously fight each Battle Boss, each one getting stronger in terms of level, scaling, items, and AI difficulty,Final Boss Veigar being the hardest with a high amount of ap to make things even more difficult. After defeating a boss, you get enough gold to buy any one item and you may go back once to buy an item. After leaving the fountain the fountain cannot heal you, the store closes, and recall is disabled until you defeat the next boss. If you defeat all of them, you get a Summoner Icon to show off your victory. Beating the gamemode with all the available characters grants another special prize like a gemstone, or hextech crate, or something else cool. Be sure to tell me your thoughts in the comments and poll and to 1UP this post so Riot can see the idea!
