Well,, you could do it manually, since you have a bootable uSD
gdisk emmc to match SD, expand fs later
then save emmc boot sector, 34 sectors for gpt,,, dd 1st 16M -> emmc, restore emmc bootsector
Then copy partitions, however you like (cp -a, gzip|zcat|dd, clonezilla externally)
then edit extlinux.conf, fstab (or boot.scr??) on emmc
if it doesn't work, you still have SD to fall back to
