My ADSL router only has a valid (nonroutable) IP address because I want
to be able to get to its configuration interface from within the
firewall. I could remove that and it would work perfectly well.

Well, actually the router firmware won't let me remove its IP address,
but there's no technical reason why the ADSL router itself needs any
sort of layer 3 presence, as long as it's running in half-bridging mode
(i.e., transforming PPPoA on one side to Ethernet on the other, and vice
versa, without paying any attention to the packet contents at all).
