This is exactly what I do, with the same filename vhost.conf and
everything =)

In fact, apache's httpd.conf is configured to read vhost.conf, but any
of my web-based admin tools (which I wrote) use a file called
vhost.latest, then this script runs as a cron job every 3 minutes:

#!/bin/bash

diff /etc/apache/vhost.conf /etc/apache/vhost.latest >/dev/null

if [ $? = 1 ] ; then
	echo >/tmp/thisisnow `date +%Y%m%d-%H%M%S`
	cat /etc/apache/vhost.conf > /etc/apache/vhost.conf.`cat /tmp/thisisnow`
	cat /etc/apache/vhost.latest >/etc/apache/vhost.conf
	echo >>/var/log/telcust.log `date +%Y-%m-%d-%H-%M-%S` INFO: Rotated vhost.conf
	echo Rotating apache configuration!
	echo
	apachectl configtest

	if [ $? = 0 ] ; then
		apachectl stop
		sleep 1
		apachectl start
		sleep 2
		apachectl start

		pidof /usr/sbin/apache >/dev/null

		if [ $? = 1 ] ; then
			echo >>/var/log/telcust.log `date +%Y-%m-%d-%H-%M-%S` WARN: Apache did not restart
			echo DID NOT DETECT ANY RUNNING APACHE PROCESSES!!!
			echo
			echo End of /var/log/apache/error.log follows
			echo
			tail /var/log/apache/error.log
			cat /etc/apache/vhost.conf.`cat /tmp/thisisnow` >/etc/apache/vhost.conf
			apachectl start
			echo
			echo I have restored the old config file and restarted apache.
			echo You will get this error every three minutes as an incentive
			echo to fix the problem in /etc/apache/vhost.latest !
		else
			echo Detected apache processes have restarted OK.
		fi
	else
		echo 
		echo >>/var/log/telcust.log `date +%Y-%m-%d-%H-%M-%S` WARN: Apache conf failed syntax test
		echo Oh dear, the new apache config failed the configtest.
		echo Will restore the old config and not restart apache.
		cat /etc/apache/vhost.conf.`cat /tmp/thisisnow` >/etc/apache/vhost.conf
	fi

fi

The vhost.latest simply contains lots of <VirtualHost> blocks.
