You can get an IPv6/IPv4 tunnel, but you can't NAT a v4 subnet to a v6 address. They're different stacks and wholly incompatible with each other
It can be done, it's called NAT-PT.

But you most likely don't want it because you will lose information on the source IP address of the traffic. There is simply no way to cram a 128 bit source IP into a 32-bit field. So it will be hard to track down and report abuse.
