Riot games should make a demigod champion. It would be like what ever his name was and his description would be son of Zues. And then his skins would be son of Poseidon, son of Hermes, son of Athena. Etc. I don't know but I think that would be a sweet idea.
How about Olympian skins? Jayce - Son of Zues: He kinda has that whole super strong, lightning god thing going for him already. Nami - Daughter of Poseidon: ... Enough said Karthus - Son of Hades: He is fond of death, sends souls to his father.
They could be wearing togas or have armor kind of like in the new Clash of the Titans, or Wrath of the Titans movies.
Someone llikes Percy Jackson :P
