I think that, once the suggestion of replacing single member elections with anything approximating proportional representation is made, the focus on managing the electoral system we DO have is lost.

Tons of measures made by political scientists about gerrymandering implicitly value PR or nearly-PR as the standard of justice and fall into this trap. But I think there's opportunity in the SMD systems for fairness, like the Gelman-King stuff that looks at equalizing the winners bonus provided to parties. That is, taken alone, it doesn't matter if seats are awarded disproportionately to votes won, as long as the system responds in the same way when the tables are turned.
