It's funny how this situation works. I mean the revolution in the Church in the 60s and 70s and the worldwide utter chaos it brought with it was many times worse than whatever the current pope dreams up.
+ABL dealt with the popes face to face on numerous occasions in those days, if any trad on earth would have gone sede, +ABL would have done so right then and there - if he was ever going to.
Fr. Hesse I don't believe he would have gone sede either based on his sound Catholic principles, but between the two my guess is that if one of them was going to go sede, it would be Fr. Hesse because he was NO and NO educated before he converted. Many of those who were NO, especially the educated ones, all seem to have the same idea as regards false obedience to the pope as Fr. Fenton taught, so if that idea resurfaced within him, then imo would be his best chance for him to go sede. Otherwise, no.
