Extra rewards for reaching plat?

In the past, the highest ranked rewards tier you could get was at Gold. Even if you managed to hit plat, diamond, etc, the only difference was the color of your border, which really ends up equating to personal pride instead of an actual reward. Now in season 6, boosting has become commonplace. Players that never even belonged in silver will be cashing in for their victorious skins at the end of the year, meanwhile people who worked really hard to get beyond this get nothing extra. There has never been real motivation to go beyond gold, and now that ranked has lost its competitive spirit, there is hardly any reason to even bother trying.

I propose that Riot give a bit of extra love to players that reach ranks beyond gold. I know that Riot has already announced that they are considering "physical rewards" for players that hit challenger (http://na.leagueoflegends.com/en/news/game-updates/competitive/riot-pls-ranked-pls), but what about the rest of us that slaved over this game and came up short of the top? Let me know what you guys think. At the very least, I feel that Diamond players should get something more than just the skin (and I'm plat, btw, so this isn't purely self-serving. Just proposing that Riot do something to make higher elo a bit more rewarding).
