June 18 - Hamilton delivered his plan in a speech that "occupied in the delivery between five and six hours" This is the speech that led to the famous charge that Hamilton advocated a monarchial system. This was denied, and it was replied, that "he proposed a system composed of three branches, an assembly, a senate, and a governor."[2] There are several versions copied down, all of which specify the Executive "to be a governor elected, during good behavior, by electors chosen by the people in the election districts" (with slight variations in wording).
Hamilton's more detailed plan given to Madison at the close of the Convention, states in Article IX § 1, No person shall be eligible to the office of President of the United States unless he be now a Citizen of one of the States, or hereafter be born a Citizen of the United States.[3]
This plan differs from that presented June 18.
According to a letter[4], Hamilton was chagrined when his plan (June 18) failed and he left the House in disgust (June 29), he returned however on a subsequent day (July 13?, August 13?) and delivered his sentiments in writing, then went to New York (August 20-September 2).
There is no record of any presentation by Hamilton on July 13 or August 13, although this does not rule out any written transmittal. If a written plan was delivered it may be lost.
Hamilton claimed the detailed plan given to Madison delineated the Constitution which he would have wished to be proposed by the Convention: He had stated the principles of it in the course of the deliberations.[5] It is true that he propsed a system composed of three branches, an assembly, a senate, and a governor. Although details vary it is the general structure of the government adopted. The detailed plan may have been political cover[6].
There is no way to know if any delegates knew of Hamilton's "born a Citizen" idea. The record does not support any claim that they did.

[4] Anonymous Letter to Alexander Hamilton. New York Augt. 30th. 1793
A publication appeared some time since in Greenleaf's paper, charging you with having moved in Convention that the Goverment of the United States should be by a King, Lords & Commons--I took some pains to discover the author of that piece, but without success -- But a conversation lately happened between Comodore Nicholson & Mr. Leonard Bleeker, in the hearing of others, in which the Commodore said; he had read the piece before alluded to, but doubted the truth of it untill it was lately confirmed by Mr. Abraham Baldwin, who was also a member of the Convention--This Mr. Baldwin did publicly in a pretty large company at the Commodores own Table. He said your motion was seconded by Mr. Gover Morris & that you was so chagrined when it failed that you left the House in disgust; That you returned however on a subsequent day, delivered your sentiments in writing, & Came off to New york, declaring you intermeddle no farther in the matter -- Notwithstanding you returned, & assented to the Constitution as it is -- This writing he suggested contained your Ideas of the kind of Government proper to be adopted -- In repeating from other persons, words are often changed; but the foregoing is the substance of what the Commodore reports Mr. Baldwin to have said -- I leave to yourself the expediency of taking any notice of it.[5] http://memory.loc.gov/cgi-bin/query/r?ammem/hlaw:@field%28DOCID+@lit%28fr003449%29%29http://memory.loc.gov/cgi-bin/query/r?ammem/hlaw:@field%28DOCID+@lit%28fr003294%29%29
[6] Jared Sparks visit to James Madison, April 25th, 1830
recounts an anecdoteIt is well known that Hamilton inclined to a less democratical form of government than the one that was adopted, although he was a zealous friend of the Constitution in its present shape after it had received the sanction of the Convention. He considered it less perfect than it might have been, yet he thought it an immense improvement on the old confederation. He drew up a plan in accordance with his own views, which he put into the hands of Mr. Madison, who took a copy of it, and returned the original to the author, telling him at the same time that he had preserved a copy. Mr. Madison says he knew not Hamilton's motive for doing this, unless it was for the purpose of securing a written record of his views, which might afford a ready confutation of any future false statements respecting them.
