A Stones/Minerals/Gems skinline

I was thinking...what if Riot create another AU skinline where the magic comes from minerals/stones/gems? We already have some types of this skins. Amethyst : http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Ashe_5.jpg Jade Fang: http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Cassiopeia_4.jpg Viridian(Maybe is a bit forced): http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Kayle_2.jpg Bloodstone: http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Lissandra_1.jpg Marble and Obsidian: http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Malphite_3.jpg http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Malphite_4.jpg Emerald and Bloodstone: http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Taric_1.jpg http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Taric_3.jpg

I think can be added Blight Crystal Varus and Forsaken Jayce in this Universe. This skinline type, for me, have a realy big potential design, variety and no limits with the champions, because all can have his types. Stupid random example: Moonstone Sunstone Bloodstone Cobalt

Maybe i'm wrong and probably it does not interest anyone, but is just one simple idea. Btw, sorry for bad english, i am only a stupid italian guy.
