Just to put an idea - I "share" my guest rootfs readonly simply by
having an rsync between the boxes on updates, which occure only if I
patch/update a server. You might even automate this using inotify.
The guest data is pulled in by an extra replicated disk - as I have only
two nodes, I use drbd, but you can use any other clusterfs here too.
So you do not need to find a fs that supports unification.
