Limited skin shards idea

Like the title says I was thinking of ways we could possibly get limited skin shards for special events, maybe a very small chance for a pass event or a guaranteed skin at the end of the year if you have honor 5 for example. I think in that way people will try to behave and be less toxic while also tryharding more so they could possibly get something valuable and "tangible" at the end of year instead of just the victorious skin every gold players gets. I really want to get either TF Pax or UFO Corki but I can't purchase for my account anywhere and according to this rare skin article Riot is not likely to put them up for sale. What do you think about my idea, do you you belive such a reward can actually make a noticeable difference in players behaviour or if you are the owner of one of those skins would you mind it alot?
