Thoughts on Profile Overview Background Customization?

The champion that appears in the overview section of the profile should be customizable in the sense that: -You can choose which champion appears -You can choose what skin you want the champion to appear with

The current overview shows a champion at seemingly semi-random, usually a champion I played recently. This recommendation would allow me, as well as other players, to express their play style, personality, and/or aesthetic interest through different skins and champions. For example, I really like the new Dawnbringer Riven skin, however I don't play riven nor do I own the skin. I would choose that skin in the overview section purely for aesthetic value.
