My suggestion is to utilize a mathematical optimization hueristic to minimize the district boundary sizes.  I think a linear programming model will work.  Input the relevant demographic and geographic information and the number of districts and the computer will output the districts.  Initially compute results using largest legal maximum district population size variances and then keep re-running with smaller variances until the problem is infeasible or the districts are all exactly the same size.

Maybe, but if there is a solution to a real problem then we cannot know if the solution will be adopted without giving it a try.
