As the tin says, with a POD of the founding of the Republic, have 5 to 7 families dominate the Presidency in such a way that it is assumed that one of them will be President at any given time. You cannot change the Constitution to guarantee one of the families is in power, it just has to be a de facto thing. For purposes of this, both Washington's adopted children/their descendants and the descendants of his siblings may count toward the same Washington/Custus family.
