No amount of evidence that Jesus was a mere human, no matter how great or how credible, would shake the faith of devoted believers. However, this new information might serve to dissuade potential new converts, although "born again" experiences rarely occur for intellectual reasons, I've observed. If people want to believe something badly enough, they're going to believe it, no matter what. Evolution, for instance, didn't much dent Christianity, even though it's a widely accepted scientific theory which directly contradicts the Bible.
You might want to add that evolution is also a widely discredited theory.
Oddly enough, those who hold fast to it take on the appearance of any of the myriad religious fanatics they attempt to demean...
***this new information might serve to dissuade potential new converts***
I doubt it. His sheep know His voice and will respond, regardless of any such nonsense.
