Yes, that sounds feasible. I'm not sure how Ceph identity / permissions will work in that case (i.e. who has access to which data, how Ceph will correlate tenants in OpenStack both through Cinder and through a direct relationship). In principle though, as long as the networking is arranged so that IP addresses and routes enable traffic to flow between your tenant network and your Ceph network, and as long as both sets of machines can see the Juju controller, they can exchange messages and traffic.
