They will also declare "This is the result of the Pope's consecration of Russia and the start of the Period of Peace and restoration of the Church."
Yes, the SSPX always appeals to false piety and other false virtues (especially charity and prudence).
I'm willing to bet that they will first call for a worldwide novena / rosary crusade, then proceed to announce the consecration after the tallies. What the faithful will not know or believe is that Menzingen has / will have already settled a deal with Rome about the new bishops, before they even called for the novenas / rosaries.
Then, the consecrations will either be openly approved by Rome, or Rome will refrain from condemning it, perhaps by being ambiguous, perhaps by staying absolutely silent about it (the clerical diplomats from Rome AND Menzingen have no shortage of tricks up their sleeves). Regardless, Huonder's attendance / participation at the consecration will let us know that it is in fact approved by Rome. The new bishops will not work independently of Rome, they will be recognized and they will maintain communication with the Roman offices, they will be prelates of Francis openly or “in pectore”.
Menzingen will then stage a big show of fake thanksgiving to Heaven and to the faithful for their 15 million-or-so rosaries, that (i) they now have new bishops, and that (ii) the consecrations were approved / not condemned by Rome.
Needless to say, I think we can rule out the possibility that the SSPX will consecrate new bishops against Rome's wishes in 2023. Although, like Fr. Chazal said, it would be the greatest blow they can deal to their traditional Catholic critics.
