While technically it can work (if your default gateway has addresses in
both networks bound to the NIC that faces inside), I'd chalk this one up as
"bad network design".  You'll have headaches.

First question I'd ask is why you feel you need "public" IPs on some machines
and not others.  Are these machines that are going to be accessing the 'net,
or accessed from the 'net?  If it's the former, use a firewall with address
translation.  If it's the latter, still use a firewall that has address
translation, but also consider moving the machines that need to be accessed
from the outside to a physically seperate segment (a so-called DMZ).  In
this case, your firewall would have 3 interfaces, in, out, dmz.
