It is rather difficult to implement this.  There are some combinations
that are illegal.  Also, remember that Parted supports many different
types of partition tables.  What you're saying is probably doable,
but I haven't been able to find a simple clean solution yet.

BTW, how would users specify the permutation?  Could you give
some pseudo-screenshots?
