I think the only real impediment is SSPX refusing communion. As you can see from this letter there is at least a major segment that is adamantly against even DISCUSSING reunion with Rome.
Schism for the sake of schism.
"Schism for the sake of schism."
Yet post No. 24 directly below yours, from Cardinal Hoyos, specifically states otherwise. Rash judgment on your part? Or a simple misunderstanding that you would wish to correct?
I'm confused. Cardinal Hoyos says the opposite of you, and he met the bishops.
