It's theoretically possible but really messy. You'll still need an entry in
aliases for each list eg:

listname: "|/usr/local/bin/procmail -m /etc/procmailrc"
   and /etc/procmailrc will be rather universal, first running spamassassin
followed by something like

:0
|/etc/mailman/mail/wrapper post $LISTNAME

the tricky part is figuring out how to pass it the $LISTNAME param.
The only way I know to get the listname is from some massive processing of
the message itself, probably parsing it from the List-Post: header (but only
if it exists ie what if you have other mbx'es on the list machine receiving
mail...)  so if you do figure out how to do this, I'd love to see it.
Otherwise, my feeling is it's not worth it to do it this way
