This seems the wrong question to ask.

Shouldn't you instead be wondering, how can you get the PIX to forward
connections to HOST-B instead of to HOST-A?  The PIX is a full firewall
with NAT features, so it can perform the NAT instead of your BSD box,
and since it is the default gateway for return traffic, will have no
trouble applying the translation in both directions.

I realize this is a FreeBSD mailng list, but you should go for the
simplest solution, because complex solutions tend to fail in complex
ways.
