That is a good idea worthy of looking into.
Actually real recently I was listening to a former Congressional candidate (Ben Knoop, 4th dist. vs. Oxley) talk about these reform issues, and he made the claim that he's seen software similiar to what you're describing, which is already used. However, It's not being used how you described. It's being used to gerrymander, and seeing how he was a democrat he's probably praying for the chance to use it so he can win a seat. It's hard to tell how credible his claims were and what his intensions of making them were. If you know what I mean.

"It's being used to gerrymander,"

Yes, this is real.

The other would work, though.

The code would be published and discussed.

The hard part would be the political fight, not the code. Politicians hate this idea with a passion.
