A new game Idea! Listen UP!

So. I was playing a great game on my pc called Naruto Ultimate Ninja Storm Revolution, and It is a fighting game, like any other. But different at the same time. While playing, I realized how awesome it would be If Riot made their version of this. I know that Instaburst is making a 2D league of legends fighter, but I would like to see riot take it a step further. Like an actual game based off of league, with all the characters, lore, stories, and etc, but like a fighting game, Just as the game I mentioned above(please check gameplay on youtube if you havent played) So what do all of you think? I know that something like that would take a long time to pull off, but I think It would be worth it. Just imagine an awesome fighting game, like mortal kombat, but less bloody, with the same attributes as league. I would pass it on to my grandchildren.

What do you think about the idea?
