Don't even think about it.

Use sendmail's smarthost feature to forward all mail it receives for
your domain to the qmail host. Make sure your domain is not listed on
sendmail's /etc/sendmail.cw file (like qmail's locals file), and then
set the DS (I think) option in /etc/sendmail.cf to point to the qmail
host.
