The cost cost to design and construct it and extensive permitting reviews that will be required. The time and energy are best spent elsewhere.

Rutherford and Secaucus are more suburban and will be challenging without a car. Nice towns, but not super comparable to JC. Rutherford train runs infrequently, but they have good bus access to NYC. Journal Square is fine but doesn't have a lot of open space. The Heights is far from the Path but has great bus access.
