That doesn't work with the normal way to implement things. DNS information on a node is global - it isn't and can't be associated with an interface in any implementation I know of. Furthermore, associting anything received in an RA with the sender or prefix(es) of that particular RA is not consistent with the model even in neighbor discovery (the prefixes advertised vs. default router selection are separate) let alone shouldn't be visible to higher levels of the stack. While one could revisit these aspects of the IP architecture I'd be leery of making IPv6 different than IPv4 in these respects.
