I seriously doubt it's as big a problem as you think it is.

LP gains start to slow down enormously once you begin to approach 100 points - this is a measure put in by Riot to make absolutely sure you belong in a higher division/league before you promote, since it's a one-way trip. At least according to posts on the forums it'll gradually fall down to as low as 4 or 5 LP. I can't imagine how long you'd need to duo queue with someone much higher than you are to feasibly get carried all the way to Gold and still not be any better than a Bronze player.
