As a proof of concept, yes it can be done. Should it be done? Not in
either a production environment or in a situation where any of the
machines is going to have Internet access, including the firewall.

Security should be your biggest issue (although I'll venture a guess that
the top of your priority list is sharing a 'net connection). If you are
running applications on your firewall... not a good idea, all the more so
if the said box is uni-homed.
