I don't think so, any more than you can NAT IPv4 onto DECnet.  IPv4 and IPv6 
are distinct protocols with their own netfilter implementations, and the code 
isn't capable of converting between them.  Conceptually, the IPv6 NAT module 
(were it to exist) could do a superficial translation between native v6 and 
v4-mapped v6 addresses, but I don't think this would buy you much in reality.

I'm not very clear on what it is you're really trying to do.
