I think bridging *is* what you're looking for.  This is how I set it up 
at one of my client's sites whose WAN IP was within the same subnet as 
his LAN. (well, actually in his case it's OPT1, he uses NAT on his LAN)

You are right that with bridging only one interface will have an IP, but 
that just means M0n0 will use the same IP (the WAN IP) on both 
interfaces.  Is there a particular reason you need M0n0 to have two IPs 
in the same subnet?
