As I just found out (Thanks Martin Josefsson!) there is available a 
conntrack match.  It lets you match more than the three conntrack states 
you mentioned - you can match conntrack status like ASSURED, SEEN_REPLY, 
etc, as well as 'states' SNAT and DNAT (matches packets which have been 
SNATted or DNATted) and also match the original pre-SNAT/pre-DNAT IPs.
