You certainly CAN do it that way.
Being paranoid, I'm in favor of having one "box" that does firewall/routing duties
without any other apps running, to reduce the exposed "attack surface".
I used to run a Smoothwall GPL box as firewall, but like you, I wanted to do
a little something about the power usage. My "solution' was a dedicated
consumer router, which used probably (not measured) a tenth of the juice
of the old PC that ran Smoothwall. I used dd-wrt on it instead of the original
firmware.
