This one should be pretty easy...
Effectively, you want to keep the primary mirror devices, so do:
lvconvert -m0 <vg/lv>
to down convert them to linear devices.
Then remove PV1 (vgreduce), add a new disk to your system, add it to
your vg (vgextend), and finally, up-convert the linear devices to
mirrors again:
lvconvert -m1 <vg/lv>
