Oh, that. Yes, perfectly. Add the new PVs to the VG using vgextend, then
create whatever LV layout you need on the new PVs (lvcreate ... -i ... PV),
mkfs, then copy the data to the new filesystems, rearrange mountpoints,
then vgreduce the old PV from the VG.  Done. But not on-line... you can
move LVs to another PV within a VG, but you can't convert a normal LV to a
striped one.
