It's possible I suppose, but is it really critical that they are the same?
There are people more expert than I on the subject of networking, but I think
we'd all agree that different IPs (probably different subnets) would be far
preferable.
Is this for a server?
With nfs you can restrict a particular shared filesystem to a range of IPs (or
single IP) and it can be done with Samba as well. I can't really see a need
for using the same IP on both cards, unless you're REALLY running out of IPs
on the network. (and I mean you've used all the potential IP adresses)
I agree with your policy on the router doing all the NAT. you could run a
modem to a Linux box and do the NAT there, but that's what most routers do
anyway.
Best of luck,
