host apache and a chrooted gentoo apache possible?

[Dlareh]

We have a dual opteron RHEL4 box that hosts a couple of very critical websites, but has a surprisingly low load. I would like to put it to further use by hosting a couple less critical things (e.g. a mediawiki) using a gentoo chroot, since I cannot risk messing with the RHEL4's apache, mysql, etc.

Is there any way I can safely configure the hosts's apache to seamlessly redirect requests to specific virtual hosts to an apache running in the chroot? Or is there a better way to accomplish this?
