I admit I was inspired by the Baden-Württemberg "best near-winner" method, but my understanding is that most (all other?) implementations of MMP require a separate source from which to appoint the "top-up" winners.

As the name "mixed-member" suggests, the winners from this other source (such as a party list) can be seen as "less valid" and lacking a constituency.

Also I think most MMP systems require a change in the ballot papers and counting process, whereas the system I am proposing would look like a normal First Past The Post election in all cases where district boundaries are drawn "fairly".
