Not even thinking about a possibility is not accord.  3000 AD is not infinity.  Recent  popes are reacting defensively but have not been able to articulate reasons that make sense.  The 12 males apostles were chosen under the Old Law, to represent the patriarchs of the 12 tribes of Israel.   The bridegroom-bride analogy was written in a Greco-Roman patriarchal culture, but the great mystery of Christ and the Church cannot be reduced to an analogy.   All the reasons given so far are rooted in the patriarchal culture, not a convincing exegesis of divine truth.  I am not holding by breath, but it can happen and will happen as soon as a Pope decides it is time.
