Another crazy but cool movie idea

Just watched Wishmaster again tonight with my roomate... good stuff. Maybe not necesarilly a good movie per se, but it was fun so I enjoyed it. Anyway- I think it'd be an awesome idea to have a Freddy vs Jason vs Djinn! First off both Djinn and Freddy are Wes Craven. This is about the most I've thought it out to work like- Freddy "lost" in Freddy vs Jason. So let's play off of FvJ's storyline. Freddy is searching for another way to get back to Earth, and he stumbles across the Djinn. Obviously the Djinn is trying to get his army to come onto Earth, and he sees this as a way to try again. So Freddy wishes he could have his powers back. Wish granted, Freddy is killing kids in dreams again. After Freddy gets his fill, then he takes wish 2: To find and kill Jason. Freddy is sent to Camp Crystal Lake. The twist the Djinn puts on this wish is that Jason is incapable of having dreams, so Freddy is once again stuck in limbo. Then, not knowing the deal with the Djinn, Freddy makes wish #3: To be brought into the real world with Jason capable of being killed. Wish is granted, and Freddy and Jason have a battle. Freddy comes out on top this time. However, having made the 3 wishes Djinn needs, his army is released on Earth. The world is destroyed, Freddy killed, and Earth consumed by Hell. Additionally, for the first time ever, HUMANITY LOSES! Who would see that coming? It'd be the biggest diversion from the ordinary EVER! Djinn is happy so has no further need to do his wishmaster thing, and Freddy and Jason are dead. Result? All three franchises ended.

Of course, this is a rough idea. I may put more thought into it and figure out how Djinn could twist the world up with the first few wishes, but I ain't in the mood for that right now. Whaddya'll think? I think it'd be cool...
