If America was governed like EU: Instead of the Office and President, have a commission of 50 presidents. Each state chooses one commissioner. But not by election, instead let the state legislature choose the commissioner for the state. The House needs to approve the members of the commission. Instead of Senate, have regular meetings of all state governors (or someone from their offices). Also, state governors are not chosen in elections, but by the state legislatures. Keep House as it is, but House cannot initiate new legislation. They can only approve/deny proposals from commission and the governors-senate.
