Certainly a possibility. But, again, it is a matter of faith as to His divinity. If a non Christian Roman proconsul wrote a document discovered yesterday detailing miracles and the ascension that he witnessed, would it be accepted as historical fact ? By some yes, by the critics, never.
There is no historical record of Christś divinity that could exist, that would be acceptable to those who deny it, none.
So the entire question is moot, history cannot produce evidence that the deniers of the subject of that evidence will accept.
Hypothetical questions of conjecture are not meaningful to the discussion. We have to deal with the here and now of what is in any dialogue or debate on the subject..
