What about Brothers Michael and Peter Dimond? 
I have head some people throw +Lefebvre and +de Castro Mayer out there.
Well, considering they think that JPII was the Antichrist, I don't ever recall them being martyred in Rome, displayed publicly for 3 days, and then resurrecting and ascending into heaven.

I
have heard the +Lefebvre and +de Castro-Mayer idea too, I think I even proposed it as a possibility the last time we talked about this subject. It's certainly plausible, from a spiritual standpoint, given their acceptance of the terms offered in the Ecclesia Dei commission as a "spiritual death" followed by a "spiritual resurrection" through their rejection of it before both dying
exactly a month apart from each other (+Lefebvre March 25, 1991; de Castro-Mayer April 25, 1991). Not that I'm implying they ascended to heaven (as +Lefebvre open taught against EENS that non-Catholics can be saved in
Against the Heresies, which, unfortunately, makes him a manifest heretic in the external forum given he never publicly repudiated it, although he could have privately done so before death)
This, of course, would fit better given that the spiritual persecution of the Faithful which came through the heresies and scandals of JPII, if he
were the Antichrist.
