Joseph would have told the same version of the First Vision throughout his life. He would have gotten the details correct surrounding the most important, spectacular moment anyone could ever have in this life.
Joseph’s five brothers (and probably the rest of the household) that were sleeping in his room (including some that shared his bed) on September 21, 1823 would have been awakened by the presence of Moroni. They would have testified of his visit as well.
If the angel did indeed take back the gold plates and the urim and thummim from Joseph when Martin Harris lost the first 116 pages, he would have returned the urim & thummim to Joseph when he returned the gold plates to him, instead of having Joseph finish the translation using a common stone he found while digging a well.
Joseph would likely have actually used the gold plates in the translation process,
instead of putting an ordinary stone in a hat without even looking at the plates.
When the 116 pages were lost, Joseph would have simply retranslated the ‘stolen’ pages. If the pages were really stolen by evil men bent on foiling Joseph, the pages would have resurfaced in some form - either as a ransom attempt or foiled attempt to discredit Joseph. The stolen pages wouldn’t have simply been destroyed by men who went to such trouble to obtain them.
The translation of the facsimiles in the Book of Abraham would match what Egyptologists say they mean. The rediscovered papyri would also support the Book of Abraham as well.
The Book of Mormon would not mention things that did not exist in the Americas during Book of Mormon times such as horses, elephants, cattle, goats, wheat, barley, silk, steel, etc. It would probably mention things that did exist such as corn, yams, beans, squash, llamas, sloths, jaguars, and monkeys.
The BOM would be supported by archeological and linguistic evidence. Perhaps not so much evidence that we still wouldn’t need faith, but something to show that the ancient Jews could have been in America.
There would be some remains of two large battles at the Hill Cumorah where over two million people fought and died.
DNA evidence would support that the American Indians and South American peoples descended from Israel.
Joseph would have either denounced the Kinderhook Plates as a fraud, or at least said he didn’t know what they were.
The witnesses would have said more objective statements testifying of the BOM’s divinity. They would not have said things like “I did not see them as I do that pencil case, yet I saw them with the eyes of faith; I saw them just as distinctly as I see anything around me - though at the time, they were covered with a cloth”, ‘he never saw them only as he saw a city through a mountain’, etc.
Some of the witnesses should have been critics or skeptics and not related to each other. Each witness should have written their own testimony instead of merely signing a pre-prepared statement.
