Color me crazy, but the odd 126 ip space kinda makes to me. Consider that one of the more common attacks on Tor users is IP leakage from the browser. In this setup the local ip would map to a real public ip, but would be entirely useless.
I personally don't think that it's a good solution. Poor operational security can't be solved by misdirection.
