Sure, create 3 RAID1s (or a RAID5/6/10) on HW or SW then create an LVM
VG out of them, create LVs (striped if multiple RAID devices) out of
the VG.

I don't know if your using LVM now on the existing RAID1, but I
wouldn't just add them to the root VG if you are, which would also
give it expanded capacity, as it would make recovery more difficult if
you need to put the drives into a new server.
