As mentioned by others, there is a way to do this, but I'd suggest that you shouldn't want to. What's wrong with having an additional key in the authorized_keys file? If the thing you're trying to avoid is the pain of installing the keys twice, well if you're using ssh-copy-id just add the public key for the other machine into the id_*.pub file on each, then whichever you install From will authorise both. If you've got a more structured way of installing the keys (i.e. chengine, puppet etc. etc.) then just add both keys to your config and you're done. This seems preferable both on the basis that you're not having to fiddle with the host keys in possibly assumption-breaking ways, but also because it may come to pass that one of the keys is somehow compromised while the other remains secure, in which case you'll be able to boot the secure system and fix things.
