It's not that easy, RunAsFastAsYouCan. It is unlikely that this would work anywhere in the U.S. The rule used to be that in a hierarchical church, a local congregation couldn't break off and keep the land, regardless of how it was titled or who pays the expenses. Then came a Supreme Court decision in 1979, the result of which was that states could either continue to follow the hierarchical model or deviate from it (the alternative approach is usually called "neutral principles"). Where states follow the neutral principles approach, the response from national church organizations has been to get the local congregations to change the way the land is owned. The result is that the land ends up basically being owned like a trust, where it's nominally titled to the local congregation, but can't be removed from under the umbrella of the national church, who are treated like the beneficial owners. I don't know for sure that all JW congregations have adopted a change in response, but it's likely that they have. I have seen some material that indicates the WTS took steps to protect themselves in the wake of the 1979 change in law.
The case of The Falls Chuch in Virginia is an interesting case: http://www.washingtonpost.com/local/episcopal-church-wins-virginia-supreme-court-ruling/2013/04/18/51b9cc04-a82e-11e2-a8e2-5b98cb59187f_story.html. The land at issue was worth millions, and the congregation had a lot of wealthy and influential members and good attorneys, yet they lost in their bid to break away from the Episcopal Church and keep the land.
Menlo Park is another example of how this didn't work. This aside from the challenge of finding groups of elders who are willing to volunteer to be DF'd and take on the WTS and their war chest in a legal battle.
