Yes, I'm using the LA1777 cross as a rootstock. And I now have a strain with edible fruit - actually pretty good-tasting fruit. I'm not sure it is entirely stable, though.
Use of the litchi tomato as a rootstock was also successful. Those grafted plants made it through a light frost. I read later that it was being used as a rootstock in East Asia for other reasons.
Hopefully, I'l get around to posting some photographs one of these days.
You are right. A freeze that kills the leaves appears to shock the plant into ripening the fruit. Peppers are the same way. You can do the same thing by pulling the plant upward until the root mass breaks a little. The remaining tomatoes will ripen quickly.
