Do you need to?

Don't be so sure...

I don't know about looproot, but I have one system set up where the
/usr partition is loop mounted from a VFAT partition, and that works

I'd certainly like to see a variant of UMSDOS that assumes the
underlying file system is VFAT rather than MSDOS - in fact, I'm
tempted to have a go at the UVFAT file system myself...
