Well, I'm not sure I have really understood your question.
A can reach B directly, right ?
So you can do what you want with gif(4).
On A you'll have to add a route from A to B though the next-hop router
(much like you'd add a default route, but using '-host B' instead of 'default.
Then setup your gif interfaces on both ends. You'll probably need an extra
address on B for the gif interface, but I think this one can be a private
(10.x.x.x or 192.168.x.x) one.
