The best people to talk to then are the IETF DNS working group (dnsop wg), as they're the experts on DNS. RCODE YXDOMAIN, "Some name that ought not to exist, does exist." at face value sounds like the right one to use, if not, they can assign a new RCODE with corresponding specifications.
I suggest that perhaps the best way to handle this is not to use A or
AAAA records at all, but rather TXT records with specific text in the
tag (or request an entirely new RRtype, called something like MXTRUST). 
Allocating a large swath of IPv6 address space, even though we have a
lot of it, seems like exactly the wrong thing to do here -- addresses
are addresses, not tags.
