FFs didn't set up 2-party system it just sort of developed on its own. How many multi-party systems were there when the FFs were around?
The Founding Fathers did an excellent job but some of their mistakes ended up haunting us to this very day. Slavery, Immigration, Taxes, States-rights. Admittedly no one could have predicted how convoluted most of those concepts would end up. Hell, current democrats are even twisting the wording of the second amendment. I believe they would be horrified in many ways at what this country has become. I am not sure that the articles of confederation wouldn't have been a better system.
The FFs were dead set against a parliamentary system(a many partied system!).There weren't any parties,to begin with,but it became FERY apparent,VERY quickly,that that would NOT work at all;hence our two party syustem...which the FFsz WERE very much a party to.
Immigration? The FFs had a written policy about IMMIGRATION,that WE still hold to? REALLY? You learned THAT in school?
Taxes? There was a federal income tax from day one?
The Articles of Confederation? YOU WANT SLAVERY ?
Instead of delusions,I suggest that you learn some facts,because you aren't dealing with any.
