As to my list, it'd require a constitutional convention to draw up a new constitution, but you get the idea.
RECOGNIZING THAT THE US IS NO LONGER A CONFEDERATION OF INDEPENDENT STATES
* Repeal the 10th Amendment
* Abolish the Electoral College and replace FTP for Presidential elections with IRV
* Abolish the Senate
* Expand the House and create a rule to prevent states with growing populations from losing seats
* Some catch-all amendment to limit the autonomy of states, their ability to waste federal funds and dominate municipalities
RECOGNIZING THAT THE CONSTITUTION GOT A COUPLE THINGS WRONG
* Limit SCOTUS Justices to a single term of 9 years
* Implement the District of Columbia Voting Rights amendment
* Set the age of citizenship at 18, allowing all citizens to hold any office and preventing laws which deprive citizens over 18 of their freedom (e.g. Alcohol and other "controlled substances" laws)
TO PREVENT THE DOMINATION OF ELITES
* Enforce public funding of Presidential and Congressional races
* Limits on the amount of money corporations and non-profit organizations can contribute
* Require all Presidential debates to be hosted by publicly-funded media, to prevent corporate media from tilting elections
* Create an independent commission to draw all congressional, state, and local legislative districts
TO ESTABLISH CERTAIN INALIENABLE RIGHTS
* Abolish the death penalty
* Establish rights to housing, healthcare, and education
* Mandate the preservation of a clean environment, specifying the implementation of a carbon tax, the proceeds of which to fund a national basic income
