This can be done easly.

fat32 does not support the rwx and flags attributes of a unix filesysyem
among other things, so I sugest to do a tar archive of usr (eventualy
compressed with gzip/bzip2) end restore from there.

If you fallow the tar path, *it might* work, but I think you will get I
a lot of trubles due to the differeces betweend 4.8 and 4.8; trubles
like not booting or panics to app not working right dumping core, etc.

If you have space on the disk why don't you make a slice on andsymlink a
part of usr (ex.: you home) to the new slice ?

root is way to big, about typicaly 100M should be enough and to be sure
go till 250, but momre is a waste of space. You do have a symlink for
tmp to /var/tmp or something ?
