I am not sure if that is possible, annalex. I don't think the Orthodox Church knows such a concept as "theological hypothesis." Some Fathers, as is well known, have engaged in some teachings that did not withstand the divine guidance of General Councils, yet they were not considered heretics. So, there is some flexibility, a range of concepts within the Church that are not out of bounds, especially when we are dealing with Divine Mysteries which are beyond our comprehension.
But wat the Church absolutely must do is remove any ambiguity as to what our understanding of the Holy Trinity is. We cannot be of one faith if there is a shadow of a doubt that dual procession is somehow detrimental to the Monarchy of the Father and, even to the Divine Economy.
If an Ecumenical Council reaches a conclusion and an agreement on this issue to re-word the Symbol of Faith, which is perfectly within its jurisdiction, and which is binding on all members of the Church, then we shall all profess one and the same Creed, and our intercommunion will be restored -- because communion is not a means to, but an expression of unity, which is why at this point we (still) cannot share in the Eucharist.
What is theologoumena?

Of course. That is precisely what needs to be clarified, that the dual procession is of the root-branch-fruit order, not of any other kind.
