I don't see how it would be "unwieldy." The rc.conf stuff would be the
same, the only difference would be the number of rc.d scripts. What
problems does having multiple scripts cause for you?

By "shutdown process" are you referring to system shutdown? If so, what
you probably want to do is modify your _stop method to find the pid of
the vm and run wait_for_pids() on it. Reading through the comments in
/etc/rc.subr may be helpful for you in this regard.
Good luck,
