The LCS gamemode

I was recently watching Beyond on the Rift, with qtpie and scarra, and the question was asked how to promote playing with friends and the subject of if they play the differing game modes, in most cases in was a no, which I thought was the same for my friends and I, we play league to play league. the only real interaction we have outside of the actual game itself as a group is watching LCS, so why not make an LCS game mode?

a game mode where either past LCS worlds finals, regional finals, or just the big games of the week, where you get your five friends, who each assume the role of a player on the LCS team that played, they choose that player and play there role as that player did in the actual game, by playing that same champion with the same skin, runes, etc, just for that game, even if you don't own them, as that player did in the actual game, and then search for another team who then selected the opposing team in that matchup. A game mode where they don't have to acctualy stray to far away from the real reason everyone is still playing this game, summoners rift, and maybe even help promote LCS to players who weren't originally interested, so they could watch the match, then recreate for themselves and see what happens this time around.
