Can there be an American government v. 2.0?

As what we are commonly seeing, the U.S. government often gets 'Deadlocked' or evenly split over issues of policy and finance, so this thought occurred to me: This "version" of the U.S. government simply put CANNOT be the 'End all, be all' (best) version of governing possible.

Could some group, somewhere be "designing" the government which will one way replace America's current government?  If these designers were able to incorporate the best elements of the Republican ideology and the Democratic ideology, then 'update' these with the very best social and civil standards, how would the end product look?  Perhaps even the very concept of Capitalism may be improved!

I am not expecting anyone to have a single answer to this question but, the very asking of it may inspire some to think of a time in the future when the government of the United States might be replaced by version (v.) 2.0, 3.0 or something better.
