It looks to me like the whole ride could fit south of the Seaport without removing anything.
With the Jersey Devil Coaster being such a contrast in theme to Seaport, however, I can't imagine the path to the coaster coming from there.
It's hard to imagine such a theme being in a kids section, regardless.
Either Seaport will have its rides moved and the area rethemed/remade entirely, or they'll use the fright-fest trail that's usually a smoking section to make a new queue and the ride will be surrounded by trees to be "alone" in the park.
All just my theory, though.
