Yes, it is quite common to use multiple AV scanners with 
amavisd-new.  The only drawback is that it increases the amount of 
time a message takes to get through your system.

amavisd-new uses the concept of "primary" scanners and "secondary" 
scanners.  During normal operation only the primary scanners are 
used.  If *all* the primary AV scanners fail with an error or are 
unavailable, then all secondary scanners will be tried.  If all 
secondary scanners then fail, mail will be queued for later.

A common setup is to use a fast daemonized scanner as the primary, 
and a slower command line scanner as the secondary in case the daemon dies.

see the comments in amavisd.conf.
