RDS Disk Design Question

We're looking to deploy 100 "personal" VM's with RDS 2012.  We are running these VM's on Server 2012 R2 Hyper-V, however our NetApp is running 7-mode and seems to be unable to host SMB3 shares to use for my VM disks.  How would the following scenario play out?

Create Server 2012 R2 file servers on our VMware Farm, with the VMDK's hosted on the NetApp via NFS.  From the Microsoft file server VM present SMB3 shares to Hyper-V for the personal VM's.

This seems to be the only away around not having to do a cluster mode upgrade to our filer.  Unless anyone else has any suggestions?  I would use local storage, however we're looking to cluster two servers to make the environment HA.
