What if it isn't that the mistake was with the sun, but his mother. We don't have any of Ozpin's backstory, so it is entirely possible that he had a fling while he was younger that resulted in a child. And Ozpin ran away. It would be a huge source of regret for him now, later in life. That would mean Ozpin never meet his own son, so he would have no way of recognizing Mercury. He might think something is up with Mercury, like a six sense that there is something about him, but it would be mostly speculation on Ozpin's part until he could find some proof, which could have been destroyed by Cinder already.

While the idea itself seems a little bit of a long shot, it would be an interesting development for both plot and character building.
