I'm not sure I quite understand why you'd want to do this? Adding extra
routers in front of your internet connection is just adding extra latency. 2
m0n0walls are no better than one given the scenario you painted.

The only times I can see where 2 m0n0walls are useful is in dual-WAN
configurations.

If you really did want to do as your scenario suggests, you could plug the
second m0n0 into an OPT interface on the first box on a filtered bridge with
WAN. That way you could give your 2nd box a public IP.
