Thanks. 

But that still wouldn't help if I wanted to re-size the RAID 1 volume
itself, would it? My understanding is that this would be useful if I
wanted to re-size the LVs. 

At work, with hardware RAID on an HP server, I recollect doing something
like take out one of the disks in a mirror volume, replace with a larger
disk, add that to the mirror, once mirroring is complete take out the
other disk, replace with a larger disk, add to mirror, and thus end up
with a RAID 1 volume that is larger that it was initially. Then the
partitions on that volume were extended (this was a Windows server). I
thought something similar might do the trick here.
