That's certainly *a* historical precedent, though certainly not the only one; the Morman migration to Utah has also often been compared to the FSP effort.
But the real genesis was the liberal relocation to and social subversion of Vermont, as suggested by an article that appeared in PLAYBOY magazine in the 1960s [link available upon request; along with one of the best of the original calls for a FSP and the one that got me aboard the porcupine wagon.
If you look at the FSP membership's growth chart, you'll notice a considerable spike and climb in the numbers of those joining once the first thousand members had signed on, of which I was one. There was a reason for that, and you'll soon see it happen again, I believe.

That's a good one, I hadn't thought of that. Fortunately, the FSP doesn't plan on holding a vote on an issue dividing the country into soon-to-be-warring halves in a disorganized territory that both sides have ready access to. Plus no outlaws, like you said. (Maybe pot smokers, but they'll be baked, so it's not a problem.)
Haven't really thought about joining. Here's the rub, each generation only has a limited number of libertarian/conservative motivators and high performers. If they abandon their home states, the net result would be a overall greater loss of freedom nationwide in a generation. Stronger Fedgov, and jealous masses vesting to loot on the borders.
I have considered joining, but I'll wait to see how it devolopes for a little while first.
I'm not sure you need to worry much about the inter-generational effects of libertarians moving to one state, though, since most libertarians become libertarians because they read libertarian books, not because of personal contact. A successful libertarian state might persuade people who wouldn't otherwise consider it.
