For one thing the theming will not be joker because his main colors are green and PURPLE, not black. I do think the theming will be the Green Lantern, or the Krypton Comet.
The ride could probably not fit in the Gotham City section unless this happens.
1. The Park completely demolishes Grizzly run
2. They move the sky coaster.
3. Hang half the ride out over the water.
Then, how would people get over to the Raging Wolf Bobs. If they walked underneath, there would have to be at least 15 feet between the track and the path. That would leave the largest drop to be only around 100 feet, minus the 15 to 20 feet of drop the ride needs to get going of the top of the hill, and turn over to flying. That would leave a 80 ft. drop, and only small inversions could be used with the minimal speeds that the drop would produce.
