vreplica and windows 2012 r2 backups combined

Hi

Hi

I would like to know if the following is possible with hyper-v 2012 r2 vreplica 

Host 1 - running 4 vm's and replicated to host 2 (same site)

Host 2 - running 4 vm's and replicated to host 1 (same site)

Host 1 - carrying out native backups of vm's to a NAS (local site)

Host 2 - carrying out native backups of vm's to a NAS (local site)

then for host 1 and host 2 to have their vm's vreplicas extended to a DR site (different location)

Maybe the design above is simply too cumbersome and a hyper-v cluster locally would be a better option combined with vreplica from both hosts to a DR site (standalone server) - 50Mb link between locations

Thoughts appreciated.

Regards
