HSG80 storage question

I have a SAN attached to my systems and we're running low on disk
(mostly because they forgot to spec for test instances of databases
when setting disk requirements). For our production instance, which
isn't in production yet, all of the disk for database purpose is
mirrored then striped. Since we don't really care about the redundancy
of those sets at this time, we are wondering if we can break the mirrors
on one of those sets in order to gain disk to use for some of the test
instances and installation files, then re-mirror them when we're done
with that. Is this possible? What's the best way to do it?

Here is the output of "show storagesets" on the hsg80 in case it helps
someone...
we'd want to split MIRR_0...MIRR_4 without losing DVGRPSM0 for example.
