Term limits, flat tax, abolish the IRS, school choice, etc,etc,etc.
None of it will EVER happen. Pipe dreams.
At best, if focus was only on one single topic (like term limits)....you probably could make a dramatic campaign across the US to have a Constitutional change fixed up. But it would take a massive push like we haven’t seen in seventy-odd years. And I would suggest the text be limited to only 30 words max....to avoid any complication.
