Magma and CouchStore Buckets in Same Cluster

East SE team had discussion on the Magma storage option in 7.1. What we notice is that the data path is set at the server level for data service and storage option is only at the bucket level. If we have one bucket with CouchStore and another bucket with Magma storage in the same cluster, and given its the same data path, how will buckets leverage the storage used?

It would be very important to have an option to be able to specify different mount points/paths at the bucket level so that customer can leverage both storage options in the same cluster if they would like to have one bucket with CouchStore and another bucket with Magma.
