How many Concept Champions created?

I have tossed out a couple concepts and noticed many, many others with enthusiasm for creativity. But I am left wondering, with all these concepts, how many, if any, have actually been accepted into use?

Now obviously only a small percent of all these brilliant and ambitious ideas are going to actually happen. But of the champions that are now in use, how many are inspired by or directly modeled after a player concept? Are there any statistics?
