I really want snow bunny nidalee or leopard nidalee, is there any way i can trade for it?

i have unchained alistar, spooky gangplank, sailor gangplank, dino gnar, riot k9 nasus, haunting nocturne, dragonslayer pantheon, madhatter shaco, riot girl tristana, veigar greybeard, tundra hunter warwick, high noon yasuo, and shockblade zed. i would literally trade any of these skins for one of the nidalee skins, and i would probably trade like 5 of them for it too. I really want one of these skins, this is the 3rd board i have made about this, and i am willing to make hundreds to get one of these skins. PLEASE someone help me
