Bringing Back Championship Skins?

As of today there are hundreds of people looking on how to get Championship Riven and Championship Thresh. As far as it goes, there were codes given away at live events and these skins were available for a short time for purchase. Hopefully in the near future, riot will put back these skins for purchase after many more. These skins are some of the rarest and most pricey for those selling them. With enough support and want for these skins to come back, riot could look into possibly bringing them back again for a short period of time.
