At the time they were faced with massive plot leaks (as demonstrated). It's possible, but highly unlikely. I have seen no evidence of any such thing, with the exception of the scene your trying to claim was fake, one in which the actual actor involved made no such statement. Jon was nowhere around this particular scene, and would have no knowledge of it fake or otherwise, he was on location in an entirely different country. I take Kit's statements as understandable damage control. Remember that Kit also emphatically stated that Jon was dead at the end of season 5. How did that work out?
The exact opposite is true, there was no reason to play this long con, it makes absolutely no sense in story.
I not even sure what your saying here. her oh shit moment was when she learned, once again, LF had been playing her all along, pitting sister against sister.
LF was helping to exaggerate those fears, Bran set the record straight. He also could have explained to Arya in more detail all that Sansa had gone through (speculation on my part). In the final scene, one in which the sisters have reconciled, Arya states to Sansa, "your right, I could have never gone through what you went through". So it's obvious that a reconciliation had happened. Sansa then reply's, "yes you could have, your the strongest person I know". That whole final scene makes zero sense when viewed in the context of your version of events. There would have been no need for a reconciliation, and no need to keep "acting" as LF was already dead. If your version of events were true, the girls would have been High fiving each other and congratulating each other on a job well done.
The fakes scenes being shot was common practice, not just for Jon's character.
So, you and this tabloid article want me to believe that the same Sansa that was disrespecting LF in the beginning of the season and hated him for selling her to the Boltons was again in the process of being fooled by him? A big part of him convincing her Arya wanted to kill her was making her believe Arya wanted to be Lady of Winterfell... and Sansa believed that? I don't see how.
While you say it doesn't make sense if it was a long con and only makes sense if it wasn't, I think in order to do that you have to play dumb and overlook a hell of a lot. For one thing, you say the ending scene with them is them reconciling after all that intense friction between them but, in truth, the ending scene is a lot like the scene between them in the beginning when Arya arrives. It's all the stuff in the middle that doesn't make sense. If it was as you and the tabloid say, I'd expect some apologies.
Bran meets with LF before Arya arrives and LF gives him the dagger which Bran seems to know all about. We're given the impression he has already done his research on LF when he has instant recall of the Chaos is a ladder thing. Regardless, both Bran and Sansa know of his crimes against the Starks but now Sansa, who he sold to the Boltons, is going to trust him again and let him manipulate her into believing Arya wants to kill her so she can be Lady of Winterfell? I can't believe that for a minute.
Then LF is going to trick the trained assassin and deceiver into finding the note he plants for her while sneaking a peak around the corner? Come on, man, can we be serious?
Arya, who knows of Sansa's hate for Joffrey from their first meeting, is then going to posit that Sansa betrayed their father and brother for her "dear Joffrey?" OMG, make it stop!
Then Sansa, who fears Arya is looking to kill her, sends her freak bodyguard, Brienne, away? Makes sense, huh?
Then the kicker, the article would have us believe Sansa bought everything in the following scene hook, line and sinker.

Sansa is going to assume the worst about Arya cause the guy, she already knows for certain killed her uncle and aunt, told her to? And she really thinks her sister wants to be a Lady? If that sits well with you, then believe it. But for myself and most viewers, it doesn't make a lick of sense. If you were to look at those many episode reviews done on youtube, you'd find 99% were left with the impression it was a con by the girls all the way through. Why? Cause it's the only possible way it makes sense.
