Perhaps if people are convinced they need two houses of parliament (and many
people I speak to are) a lower house could be elected in districts and a
smaller upper house could be elected by nation-wide PR.

There seems to be a distinct logical problem with using a pairwise count to
elect a number of candidates.  STV works well for PR because it operates
much more like a plurality system.  I can't see an obvious way to use a
pairwise count for a multi-winner election.  I suspect the answer, if there
is one, is rather more complex.
