In a LE it would be mirrored too and a copy would be in each mirror...

Yes, but this will have the side effect of not ensuring separate PVs
for the mirrored LV? An the mirror log would still not be mirrored, so
in a failure situation you would still face data loss or force a fully
resync of the mirror.
