Generally speaking, this is not possible to do.  Interleaving describes
the number of sectors which are read out of the number that pass beneath
the r/w heads.  So, for example, an interleave of 1:3 takes three turns
of the disk to read the entire track.  Needless to say, the sectors are
positioned in a like manner; i.e., sector "1" and sector "2" have two
other physical sectors between them.

While I suppose you *could* change the interleave factor, the amount of
data shuffling you'd have to do to make it work properly really wouldn't
be worth the hassle.
