Custom Lane Cosmetics

Hey guys, just an idea I had bouncing around, I saw the new ideas for S9 and something they mentioned was ideas for "lane mastery". So I was thinking, why not have custom cosmetics for whatever lane you have the most experience in? Via starting from your base and working tore the middle or just minor suddleties through out depending on many things you can unlock, or just gain from playing a specific lane? I think it would add a good bit of pride, and just an over all interesting edition to overall game play
