Change Ingame Splash art

Hey, I want to change the ingame splash art of the winter Orianna skin to this https://bogan666.deviantart.com/art/Elsa-X-Orianna-Character-Mash-Up-499408974 . (at loading screen and maybe champion select)

I've heared about a lol_air_client but this is out of date. Are there any up to date possibilities?
