I can't find any modern big-endian Linux systems... looks like all the ARM distros run in little-endian mode.
Here are QEMU images for debian-mips (should be big-endian, as opposed to debian-mipsel): https://people.debian.org/~aurel32/qemu/mips/
Of course it will run purely in software, but most likely more than fast enough to copy away the data.
Not entirely sure that particular emulated MIPS system support more than 4 drives), but it appears that a starting point could be (man qemu-system):
Instead of -hda, -hdb, -hdc, -hdd, you can use:
qemu-system-i386 -drive file=file,index=0,media=disk qemu-system-i386 -drive file=file,index=1,media=disk qemu-system-i386 -drive file=file,index=2,media=disk qemu-system-i386 -drive file=file,index=3,media=disk
with indexes 0..5, as you need the boot disk, all 4 drives, and one more as the backup destination.
May or may not be the best way, but IMO beats trying to hex-edit the superblock right away.
