Possible game mode in distant future?

I know its unlike Riot to take inspiration from other games, but this seemed like a pretty cool idea in my head that could be polished into an actual game mode players would enjoy.

So what if there was a game mode consisting of like 5 people, free for all, and there could be something like a smash ball from brawl, or a snitch from the game of quidditch, or basically something floating around the map that can be attacked and destroyed for a reward. The reward could be something like an individual baron buff, or a storm shield from dominion, or an even an enormous amount of gold.

The map could just be an open circular arena type of map and there could be various items that spawn randomly. I guess you could play something like that on magma chamber.

Various items that are spawned could be something like mini buffs. These mini buffs could be something like 3 second dodge (lets bring that back yeah?), or speed boost, or AD, AS, or AP buffs. There could even be item drops where even a zhonya's hourglass or some other expensive or inexpensive item could be picked up and put into your inventory.

This could be a free-for-all deathmatch, team deathmatch, or something like that. Whoever has the most positive score would win. I think if more thought was put into this game mode, it could be balanced to where even if you're losing horribly you can make a comeback just because of the drops. So even if you're winning in score, you can still lose the lead due to something like an item drop or something similar to a smash ball in SSB brawl. And then to reduce a big landslide victory, you could set a timer on the items picked up that randomly spawn, so after a certain amount of time it disappears from the inventory. Even in a fight an item you recently picked up could disappear and make you lose a fight.

This is just an idea I came up with. Post whatever you guys think lol
