Sadly, the answer to your question is, "No."
There are numerous people on this very forum who would tell us that, while its not a good idea, we haven't the authority to question the conciliar church on the matter. There will even be people who call themselves traditional Catholics who will, because it's the only one available, assist at a traditional "Mass" in the designated diocesan parish by a priestess (and there will be priestesses saying the traditional Mass). They will declare that the service was just as wonderful as it would have been if it had been a priest saying Mass...if not better.
There is absolutely no reason to believe that most people who have already blinded themselves to the reality of the Crisis in the Church will not be blinded by yet another travesty.
I used to think there were various things that would bring people to their senses, only to see lines drawn and crossed and have the very same people tell me that I'm the one who is being unreasonable and schismatic and refusing to accept Benedict as the true pope.
No, I'm afraid it won't matter. What's more, while I highly doubt that the SSPX will start accepting women into their ranks, I really don't know what they will say about the acceptance of priestesses in the conciliar church. One thing is for certain: When the conciliar church begins ordaining women, there will be women bishops very soon after and the Vatican will simply not be able to resist appointing women as cardinals (the first will probably be in charge of the Congregation for the Clergy) and I am absolutely confident that the first conclave that includes women cardinals will elect one of them as pope; probably on the first ballot. They will simply not be able to resist that act to "prove" they are not sexist just as so many Americans elected self-evident a communist to the presidency so as to "prove" they were not racists.
And, in case you're asking, the very same people who defend the women priests will demand that we accept a woman pope, or would that be a "popess"?
