Stephen Amell was at Kansas City's Planet Comicon and he revealed that pitched a crossover idea involving CW's Arrow and Supernatural.

When a fan asked if Amell if he would ever appear on Supernatural, he revealed that he was already working on that. "I pitched an idea yesterday to the President of Warner Bros. TV Greg Berlanti, who runs Arrow, Flash, Supergirl, just did Pan - he's a genius - and Mark Pedowitz, who runs the CW," Amell said. "I pitched something called fan-fiction live. I pitched an idea where we would take Arrow and Supernatural and write a fan-fiction crossover episode and do a live-reading."

Stepen Amell shares his desire to work alongside Jared Padalecki as Sam Winchester and Jensen Ackles as Dean Winchester at the 20:46 mark in the video below.
