I think that replacing the whole Constitution is mistaken. Popular election of the President, no longer giving states equal representation in the Senate, and an amendment to end corporate personhood and money as speech might suffice. Achieving these reforms as Constitutional amendments might not be feasible, but the Compact of States, which would effectively end the likelihood of the winner of the popular vote losing in the Electoral College, is an example of sidestepping a problem with the Constitution.
