What would you like to see as the outcome of a constitutional convention in the US charged with rewriting the country's constitution?

Many states have already passed resolutions for a constitutional convention to be called around budgetary issues. Some states have not limited the scope of their resolutions calling for a convention.

Were such a convention to occur, what would you like to see as the outcome?

Personally, I would like the US to switch to a parliamentary system with proportional representation based on voting for parties as opposed to individual candidates. It is a very different system than what we have now. I would also like to see a complete end to privately funded campaigns for office and have only state-funded campaigns. I believe this would curtail the grotesque amount of money that flows around our government officials. In an atmosphere where individual politicians do not have to depend on donations for their offices, we very well might see better and more balanced legislation emerge.
