I believe that all or most of these are available in FS 2004 ( or 2002) versions. I'll research it further.Could you also ask Paul Clawson to make a FS 2004 version of all the new palnes he made for FSX, such as the Berliner Joyce OJ-2, Northrop BT-1, Northrop A-17, Douglas O-43, Douglas O-46, Amiot 143 or Ryan YO-51 Dragonfly (very nice small bird...)?
