Idea to make Worlds more interesting

Like many of you, I found the amount of repeat champs in the world scene to be boring. I came up with an idea to diversify a bit. Champions can only be picked/banned once in a series. For example, a Nidalee ban game one means that she is banned for the entirety of the 3 or 5 game series. Picking Zyra game one means she would be unavailable for either team the rest of the series. It would make teams have to think about their future games without the champs they come to rely on every game. It should make for more interesting comps, with champions that you wouldn't normally see on the Worlds stage. With the quantity of champions available this is feasible, since in a 3 game series the max amount of champions used would be 48 and in a 5 game series the max would be 80.

Just a thought to make things more interesting.
