Sedevacantist bishops joining the SSPX? That doesn't even make sense. If the claim is that the SSPX has shown itself to be hardcore, old-school Traditional, etc. that would perhaps convince those on the left to join. But on the right? They are already 100% resist with no recognize. All their bishops were consecrated without papal mandate.
And 29 NO bishops? seriously?
If you're going to be insane, you should add to your prediction. What about the unicorns flying out of your butt? Can't forget about the ass unicorns!
