Yes, basically:

Do an alternate qmail install (qmail2)
Install your qmail-scanner on qmail2 with only antivirus scanning.

Assuming you're running supervised:
create a /service/smtp2/run that only binds to your external IP (correct
the paths)
create a /service/send2/ like /service/send, but with correct paths
change/add /var/qmail2/control/smtproutes to contain only:

modify your /service/smtp/run so it only binds to

What you did was install a blank qmail (make sure the basics are there
so you don't have an open relay, etc) into qmail2.  All it does is bind
to your external IP, recieve email, a/v scan it, and forward it to   Since is your original qmail install, it will
handle everything as it did before.

It can get confusing - so make sure you backup everything before you
accidentally edit/delete something in /var/qmail instead
of /var/qmail2 :)
