I don't see why it wouldn't work as long as you have an ISO made of SNES and the roms and then patch the ISO with the disc patcher.
i answered my own question i used image burn and made an iso9660+udf image and renamed my roms to 8+3 patched the image and burnt to dvd-r at 4x and it booted perfectly
i also found you can boot any backup or elf with ule all you do is let it read either an original ps2 dvd or cd then swap it with what you want to load then go to filebrowser then pick the slus file if its a backup or the elf if its something else and it will boot
