I’ve got to say, having been involved in campaigns to end gerrymandering, there is a subset of people who can be bothered to learn/care about how it works, and many others who don’t. Your process sounds even more complex and time consuming, and I don’t see it being effective because the general public won’t be invested in it. Like voting for traffic court judges but even more confusing.
More importantly I also think you’re underestimating the complexity of reconciling hundreds of thousands of neighborhoods per state, each a ranked choice list of different variants. One person will pick a boundary, and then some other person will pick a boundary that conflicts with it, multiply that by a dozen million and then what, some algorithm will decide which lines are correct? And then the resulting districts still won’t have an equal number of constituents? That violates the one person one vote principle, which is part of the issue with gerrymandering and the electoral college.
