It doesn't seem that the Green Party or the Radicals are in a position to make many demands of the PS, if they are dependent upon an electoral coalition with the PS for their representation in parliament.

So it would come down to whether the FDG is required to form a majority, and what price in electoral reform the FDG could extract.

MMP on whatever numbers on offer would seem to be the first best outcome for the FDG ~ any other electoral reform would be a consolation prize if MMP is out of reach.

Of all the electoral reforms ~ preferential voting, multi-member STV, MMP ~ while second preference wouldn't have as dramatic an impact, it also comes with the least likelihood of increasing FN representation, so long as the FN remains relatively second preference toxic. However, that likelihood would have been even lower before Sarkozy's efforts to woo the FN electorate.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
