Idea to improve the game

So, I came with this thought some days ago; you know how awful is to play ranked matches, and getting a toxic player, troll, etc. What do you guys think, (and hopefully Dev team) if Riot could make a system to punish and ban these players from ranked games. For example, lets say that "Toxic666swag" left to many matches due to ragequits, and, in top of the LeaveBuster punishment, he wont be able to play ranked games in the next 10 games, same punishment if "pusskiller69" fed like hell, to say another example. I think it would also be beneficial if this system punished bad players, (sorry haters) but, well, those players have to actually know they are doing wrong, because at some point, when those players CAN'T follow instructions, they keep thinkng they're doing good and that they lose because someone's else fault, in that way, they would be forced (if they still want to play) to play normal matches, where there is no problem being bad, and a lot of people practice there. I think this would improve the amount of balanced matches in low elo, and by that I don't only mean getting bad/toxic players in YOUR team, but in the opposite team, because, admit it, even if you have fun and you win, somenthing doesn't feel right if the match is to easy. Lets also think of the cons. My first thought is thay maybe, queue times will take longer, and probably, you would be playing with the same players more often. In my opinion, waiting 6 minutes (guessing) is totally worth if I'm playing a balanced match. Back to the way this system would work, just like with chat restrictions, this punishments should grow, like, being banned for 25 games after 10, then maybe 50, idk. So, do you think this could work? Comment if you think this could have more cons, or pros.[slayer-pantheon-thumbs]
