In the crudest illustration possible... Disney Themed skin line
Though I highly doubt this would be considered due to Disney and their adamant protection of copyrights, I present in the crudest fashion part of a potential Disney inspired skin line.
Including:
Beauty and her beast - Sejuani [Jungle] Bard of the Lamp [Support] Fantastical Veigar (Fantasia Micky Mouse) [Mid] Wreck-It-Malph [Top]
Not sure who for Bot lane. I'm thinking a Miss Fortune skin based on Toy Story's Jessie but she already has a skin similar to that. Miss Fortune would work best as it's essentially an AOE based team comp.
