You failed to address the other point. The imposter also has family and other nuns, still with faith, who know her.
Suddenly they pick up a Catholic newspaper in Portugal in the 1960s to 1980s and recognise someone they were in another convent with who is being put forward as the most famous nun in Portugal. Surely they would notice, suspect and go to the press.
How did they stop the imposter nun's family visiting her? Or did they get an orphan, apostate nun who wanted to play make believe for 45 years?
It is a hugely complex and risky operation. What did it gain compared to simply bumping Sister Lucia off and not replacing her. The stooge accomplished very little.

Oh, okay, I think I misunderstood what you meant when you asked this question the first time around. That's an interesting question. Maybe the imposter had been in the convent so long that her family would have a hard time recognizing her, since the last time they saw her was when she was a child or young adult. And nuns' habits cover most of the head, making nuns in general particularly difficult to identify. I could see them saying, "Gee, doesn't Sr. Lucy bear a weird resemblance to [imposter's name]?" And if someone went around saying, "Sr. Lucy looks just like my aunt who entered a convent 40 years ago when I was a kid!" how much attention would they get? People would either laugh it off or maybe think the person was a little off in the head, like someone going around bragging about how he looks exactly like some Hollywood star. People don't take that sort of thing very seriously.

Oh, my friend, it accomplished a lot. Really a lot. This was one of the most successful psyops in the whole Vatican 2 non-religion. There is no need for modernists or heretics to deceive the 90+% that you mentioned have already lost both their faith and their morals. Those people are in the bag. But there was a good section of the Vatican 2 followers in the 70s, 80s, 90s, etc. that had grown up before V2 and knew something was wrong in the Church. These people had kept the faith and good morals, and didn't like what the "Church" was doing, but didn't know what to think. Those people (and a lot of those types are still around today) are the primary target of modernist heretics, the stereotypical "little old ladies who pray the rosary all day long". Those are the ones the devil will pull out all the stops to attack. Those people are the ones who would pay attention to and
actually care about Our Lady, especially the most recent apparition of hers in Fatima. So getting someone to claim to be one of the seers of Fatima, who also openly attends the New Mass and thinks John Paul 2 was a great, holy pope, would have a powerful effect of keeping these pious people in the Novus Ordo church and away from traditionalist organizations that they are told are "not with the pope", including R&R groups like the SSPX. These people just say, "But Sr. Lucy saw Our Lady and she went to the New Mass, so it must be okay. And she loved Pope John Paul II, so he must be a good pope. Our Lady promised Sr. Lucy she would go to heaven, so you can't tell me it's a mortal sin to attend the New Mass if Sr. Lucy does so."

Whatever you think about whether there was an imposter or not, Sr. Lucy (real or fake) kept a huge number of devout people in the clutches of the New Church who would otherwise have gone trad.
