Is there any way to change the source address of an outbound ICMP packet?

Here is why I am asking.  Instead of dropping packets I reject them with ICMP 
host unreachable
packets.  If I were to try to initiate a connection to my firewalls outside IP 
I would get a host
unreachable from the same IP address as the firewall.  I would like to be able 
to change this
address to be the gateway at my ISP.  That will lesson the chances of recon and 
mess with a few
heads.  Is there any way?
