I wrote one answer, but I never saw it get posted, but I had another thought in the meantime anyway. See inline.

Presumably what you mean by this is to set a default route on router 3 and router 4 that points to the HSRP address configured on routers 1 and 2. This should work. In other words, it should allow the downstream nodes to get out just fine. My other thought was that the issue is traffic coming back. Presumably, if you do this, router 3 and router 4 aren't running a routing protocol, so they aren't telling the rest of the world about their downstream LANs. This is a problem, but fixable by adding static or default routes on other routers so they can get to those downstream LANs. Maybe someday my other message will get posted to, but if not, it mentioned that the only problem that I could find documented had to do with PIM multicast.
