What new skin themes would you like to see?

I would love to see the expansion of the reverse theme. Like Reverse Annie but for champs with pets. Yorick, Ivern, Quinn, Nunu & Wilup

A Rivals theme where champs swap outfits and personalities. Thresh & Lucian, Leona & Diana, kha & Rengar

Gender swap skins, which is probably been suggested before.

Super Sentai (Rangers) with mech recalls and poses.

Nation swap skins, like Noxis Garen, Demacia Cait, Ionia Kat, Zaun Hec, etc

Maybe animal theme skins for joke skins. Like Ahri as a fox, Gragas as a bear.

And finally a Boy Band with there daddy manager in a suit.
