I wouldn't doubt it for a second.
The fact is, even if the pope doesn't fit any of the possibilities I have outlined above, people will find a way to make the prophecy fit. For all we know, he might take the name "Pope Benedict XVI", which will be tied to the Order of St. Benedict (without him necessarily being a member), the Olivetans.
That's the beauty of prophecies... when they don't fit, people make them fit.
