Firewall-1: Can Internal Hosts Share One Public IP With Static and Hidden NAT?

We have two mail servers: one for incoming mail and one for outgoing, and
both are behind Firewall-1. I want them to be seen on the Internet as a
single IP address. Can I have a single common public address that exists
both in a static and hidden translation rule at the same time?
I would configure the incoming mail server with a static rule, so that
incoming packets to that public IP get directed by the firewall to the
incoming mail server. I would configure the outgoing mail server with a
hidden automatic NAT rule that points to the same public IP, so that
outgoing packets from that mail server get NAT'd to the common public IP.
I know this works for more than one host to share one public IP using hidden
translation, but I don't know yet if it would work with a single public IP
using both a static and hidden rule. Any advice on this is appreciated.
