OMG Success! I dumped my memory card with no saves on it, created a save of F-Zero GX in Dolphin, and imported the save on to the memory card and it worked! All I needed the whole time was to use the memory card dump.
Now because save files have to be restored individually there will be some restrictions on it. You will have to start a new save using the dump of the memory card you wish to use. Furthermore I believe the amount of other save files cannot change. So whatever save files you have on the memory card file before you create the XD game MUST always be there and never moved. I don't think there are games that change the amount of blocks the save uses or not as they simply create new entries.
