I've not looked at the specifics of your problem but it should be possible to 
use a pv or hvm backend storage 
driver domain with pv or hvm frontends.  I have used the following in all 
possible combinations:

dom0:
Xen 4.4.3, Ubuntu 14.04 with 3.19 kernel

frontends:
Ubuntu 14.04 with 3.19 kernel
Windows 2012 (recent WinPV drivers build)

backends
Ubuntu 14.04 with 3.19 kernel (pv)
FreeBSD 10.2 (HVM)

The disk for the frontends is using the form:

disk = [ 'phy:/dev/volume,xvda,w,backend=storagedom' ]

IIRC the xl config parser needs patching to recognise the backend parameter for 
this format.

Regards,
James
