Why don't keep it ipv4?
If you run MPLS VPN netowork i don't see why you want something else in core.
MPLS don't care about ipv4/6 and PE just assign labels for prefix/vpn and 
distribute it to other PEs.

For me it looks like double security here, if your core has no ipv6 i can't be 
accessed (read: hacked) from outside ipv6 world/vpns.
