The OSPFv3 spec. does support carriage of IPv4 NLRI in OSPFv3, although
you'd still require IPv6 link-local communications for the OSPFv3
process itself.

I know Juniper introduced support for this around Junos 9, and I know
Cisco have it IOS 15.

Would be nice to hear how come doing this, if you do go ahead. I'm
ambivalent about whether I would do this if I were an OSPF house.
Hopefully, I would...
