my question is how to configure 2 nics with different ip on same
box in the same subnet.

Configure the second with a /32 prefix (netmask 255.255.255.255)
instead of the usual netmask.

Surely this configuration will cause all the reply's to be routed out
of re0 without some form of pfil layer manipulation?

If both nic's are connected to the same broadcast domain, what
difference does it make which nic sends the traffic?

This could cause some arp related issues at the other end? What if the remote end point updates its arp entry because it thinks the remote endpoints address has changed (as it has a direct route to the network i.e. it has an IP in 10.200.1/24).

It may be worth the original OP investigating if_lagg as it may provide some better solutions.
