FWIW, I did that with Cinder and it was great except for one DB change we had to make regarding the server name for volumes - http://dischord.org/2015/12/22/cinder-multi-backend-with-multiple-ceph-pools/ is a pretty good description of what I saw. I suspect that was just a poor configuration from our Kilo setup rather than a change specifically related to the upgrade, but the upgrade brought it to light.
Haven't yet taken the same step with others, we're doing the upgrades one thing at a time and for some (Nova) we'll be jumping through Liberty because of the risk of jumping two steps at a time.
