Chris, I'd make a couple of quick suggestions. First would be to reframe your proposal in tone and presentation.
By tone, I'd suggest not looking at all the reasons why it shouldn't work. I noticed on your site that you're an architect. Think about the proposal in the same way you propose something to a client. You don't tell them all the things that will go wrong (being overcharged by contractors, termites, fire, water damage, floods, famine, family arguments, etc...).
By presentation, while it's okay to have a paragraph teaser, I want to know what the story is. If it's not part of the story, don't tell me. Currently the way you build it up I'm expecting the greatest idea I've ever heard and no idea can live up to that. Obstacles that need to be surmounted are not part of the story, unless...
...that is the story. Which would probably make a very interesting documentary – "Guy faces insurmountable odds to make incredible idea a reality. Does he or doesn't he?"
I would also recommend trying to hook up with someone in your area, a friend with a camera or an aspiring filmmaker, and work together on moving the project forward. As Doug mentions, it's unlikely that established docmakers would be tempted, or being tempted, it may not be in the way that you're envisioning.
You also may want to start smaller. Instead of an A-list star, why not a local celebrity in your area. They're much more approachable and the idea would be the same. It might make the idea more attractive to more established filmmakers and celebrities.
