Limited Skin Trading

On a serious note, does anyone but me feel that it would be nice if players could trade skins between themselves, with numerous restrictions to keep it from being abused? Personally, I would love this.

It could easily be contained to say, one trade a day? Or less? And also on balanced RP cost terms--such as allowing skins to be traded for their value or half it, to include sale costs. I think a lot of people use a limited skin pool, and I know that some skins come out as the 'best' for players who have collected other skins for that champion, like a friend of mine who has three Darius skins and is wary of upgrading to Dunkmaster, since the money that went into the others would then feel wasted. I myself feel the same about Fiddlesticks, for instance, since I've gotten two skins for him in Mystery Gifts (one from Rito--thank you guys) and half the time I feel like at least one is being wasted on me.

What do you think?
