One thing that comes to mind is if you could utilize it as a giant distraction on one side of the path for guests to ooh and ahh at, you could get some amazing scares from the other side of the path.
I love your idea to build up storefronts for it; I think it's all just a question of cost and benefit. You probably don't want to put too much effort into a scene like this that guests would observe from afar if you could use that same capital to give them something up-close that they can walk through. Not saying don't do it by any means, just don't spend half your budget on it! The chicken wire ghosts I think would be amazing for this area, I can see it all together in my head and it looks incredible!
Best of luck!
