Thanks everyone, especially to Kmarei for his images.
For everyone thinking of doing it, it was very quick if you do it through USB. I couldn't find my large Flash drives, so I just used my SD/CF card reader and copied each of the iso contents it to 1xSD and 2xCF cards, all formatted FAT32. It took a little under an hour and was quick and easy and painless. I used the glove compartment USB port.
Maybe someone can experiment, by coping all the contents of the pkgdb in each ISO to one massive pkgdb folder, since the config.nfm files are identical in each ISO.
