Update Battle Boss Blitzcrank/Arcade Riven Splash?

This is pretty minor, but since the Battle Boss Blitzcrank/Arcade Riven splash art is made to look like a character select screen in a fighting game, would it be reasonable to ask for an update to include skins released since then? It normally wouldn't bug me this much, but there's already grayed out spots to show characters that haven't been unlocked/released yet, suggesting it might get updated as more skins are added to the line.
