That is a splendid idea.
However, I wonder if it would not be more quickly and easily done if we were to post the list of names of priests WHO HAVE BEEN ORDAINED BY OUR BISHOPS.
It used to be that the Seminary newsletter ("Verbum") was publishing the pictures and small biography of the Priests and Deacons ordained in Winona every summer.
If we could find a way to get old issues from the last 20-25 years, or any such other source (Angelus? Regina Caeli Report?), we could then have a list of the Priests we know are validly ordained. It would be a "VALID FOR SURE" list.
Any SSPX priest NOT ON THIS LIST would automatically be suspicious. His name could be added to a separate list called: "TO BE INVESTIGATED".
If it is proven that the suspicious priest was conditionally re-ordained, his name would be removed from the TBI list and added to the list of "VALID FOR SURE" priests, and the name of the Bishop who ordained him be added.
If it was proven the the priest on the TBI list was NOT re-ordained, then we would add his name to a third list called: "DOUBTFUL VALIDITY".
I think it would be easier and quicker to proceed this way.
