Make them, as long as you give the original artists credit when you pilfer their ideas on the internet, no one cares. Do you know how many fanfictions there are of canceled T.V shows, admittedly half of them would make a true fan cry, scream in pain, yell in anger, traumatize them, or any combination of the four. Several of them are actually good and some were made by the actual authors. Who knows if it's good enough, and I'm talking about blockbuster good, theymight make it into a T.V. series.
Welcome one and All to the Jesters Carnival, where the prizes are greater than your wildest dreams, but the nightmares here shall silence you before you can even scream.
