Already owned Mythic Skins / Skin Shards

Hello, I was lucky enough to get 10+ Gemstones and forged Lancer Zero Hecarim (Mythic Skin) but now I got him again out of an "Event"-Chest (dunno which one it was). I know its pretty lucky but its also very sad for me because the only option I have is to disenchat it. I would rather like to give it away or do something better with it other than enchating. Could there be anything else if u get the same Myhtic Skin Shard twice?

Greetings Tim
