Champions look game Change

Hey there,i m sure it was already spoken but i was thinking about how cool would it be if u could see items that u buy on your champion. Late in game Riot can make skins like this,like u buy skin for Shen and items in shop are changed with icons and appearance on your champion and if u go full tank he looks different from when focusing on magic resist or even mix of all then u got new looks...u get it where i am going. I know that Riot would have a lot of work to make it true,but it would be cool that u can make your own skin true the game...

Let me know what u thing guys :)
