It's still in development state so no warranty at all but the main idea is
But if you are still on 3.5 I think that it will be easier since the
auto-import procedure to import the hosted-engine engine storage domain and
the engine VM to manage them from the engine itself has been introduced
only with 3.6.

With 3.5 you probably can do just that.
Then you have to edit /etc/ovirt-hosted-engine/hosted-engine.conf on all of
your hosts to point to the new storage device.
