I've seen your work on the yocto list. It looks like you have most of the parts there. I think the am335x will use the file system and load the mlo. So yep, it looks like you can copy the files over and the bbb should boot off of it (assuming you hold the boot button or have zeroed out the first block of emmc). At least you should get into uboot. Not sure what that roofs.ext2 is but that's probably because we boot to another partition, that may work just fine.
