No, it doesn't. First, changing constitution would be impossible. Two, even if you did all this it would just make right wing states get even more extreme (there's nothing in the plan that would let central government protect human and constitutional rights in red states).

Unfortunately US political system wasn't designed in a way that let's it change with time. To introduce big reforms like this it would pretty much have to collapse and be rebuild from scratch. Realistic way to make things better is simply organizing locally to inform/educate people about progressive/socialist policies, electing moderate/progressive politicians to take over Democratic party and simply creating a political force that can actually oppose Republicans instead of trying to comprise all the time.

No so long ago it was generally accepted that Republicans will always be a minority party. They managed to take over the government though smart PR, well organized (dis)information campaigns and long term, bottom-up work to take over institutions. Now Democrats have to do the same.
