That is simply untrue and I defy you to produce the evidence that the participants of the Philadelphia convention intended any such thing!
Actually, that was what Alexander Hamilton was pushing for in his 5 hour speech that opened the Convention. (Imagine five hours without a bathroom break!) Hamilton was pushing the idea as far as he could take it as a means of framing the issue, but no one really wanted to follow up on his suggestions. He had gone too far for most of the delegates.
