You have to be careful with this or you could end up with a moribund creature like the confederacy we had under the Articles of Confederacy before the Constitution took effect, lots of state power, to the point of agreeing to anything of a legitimate national interest became near impossible. I see nothing wrong with the representative republican model the Founders gave us, but for sure there has to be a super-explicit statement of meaning agreed to at the formation of the New Republic that nails it down.
I would take the Founding Documents (Declaration, Constitution and Bill of Rights) and combine them into a Universal Declaration of the Rights of Man and the Specific and Enumerated Limitations of State Power, and unless people agree to every single word of this charter and agree to its commonly understood meaning and know that no part of this can ever be overturned by any judge, by any legislature or any executive...we could have what we once had at our Founding. I would get down to the minutia of the very size and scope of government and any deviation from that (as well as for any public expenditure of public monies) be required to meet a super-majority approval. And there would be term limits, very little pay and very little per diem, no army of staffers, no lobbyists or advocates (it would be legal to shoot them should they even approach a sitting politician, judge or current officeholder), stuff like that...
