Hextech flexibilty

I have thought it would be a nice way of being able to share your loot you obtain with the hextech chests. For example I have a snowday Gnar skin though I don't want it nor do I own Gnar. And my premade buddy has a skin I very much want. So a sharing feature would be quite useful, though of course they would have to be skins of the same value, and the wards and summoner icons. Just spilling some ideas :) I would like to know if anyone else supports it or why it's not possible. Thx :D
