I'm not sure all Orthodox would reunite with Rome but I suspect some could. Would it be similar to the Eastern Rites which seems to me to be similar to the Anglican Ordinariate (or rather the AO is similar to the Eastern Rite) or a completely different method of reunion?
What about the Councils of the West which the Eastern Orthodox do not accept to include Vatican I which defined papal infallibility? And what about the two dogmas defined by the pope alone concerning the "Dormition of the Blessed Virgin Mary" what we call the Assumption and the Immaculate Conception?
Obviously Pope Francis is striving the develop Roman Catholic synodalty. The Orthodox bishops I believe work on this model, but strive to maintain orthodoxy not novelty.
And what about the theology of the Sacrament of Marriage that does allow for a non-sacramental marriage after a sacramental one has "died" which I believe is a part of the theology of marriage, meaning if the marriage is so corrupted by division that it no longer is the substance of the sacrament. I am sure those more knowledgeable about Orthodoxy will chime in.
I think in this country we would have a bit of a hard time working out some kind of unity as I think many Orthodox communities fear the Latin Rite taking their sheep from them. I could be wrong about this, but it is my sense of things.
At any rate, this development is interesting:
Orthodox Patriarch of Constantinople rebukes Moscow, underlines importance of ties with Rome
Catholic World News - September 04, 2015
Orthodox Patriarch Bartholomew I of Constantinople underlined the importance of ecumenical ties with Rome, and criticized the resistance of the Russian Orthodox Church, in an August 29 address. The Ecumenical Patriarch—recognized as the “first among equals” of the world’s Orthodox leaders—stressed the primary importance of ecumenical affairs, and reiterated that his role involves “protecting the unity of the whole Orthodox Church.” He said that opposition to ecumenical unity reflects a “diabolical” impulse. Patriarch Bartholomew said that his continuing contacts with the Holy See are a critical component of his ecumenical work. He expressed his enthusiasm for the planned worldwide Orthodox council, but conceded that it cannot accurately be described as an ecumenical council “because Western Christians are not invited to participate as members.” The Ecumenical Patriarch—who has frequently sparred in recent years with the leaders of the Patriarchate of Moscow—clearly appeared to be criticizing the Russian Orthodox leadership when he spoke critically about Orthodox bodies that “maintain intimate connections with the government of their land and enjoy abundant financial support,” and advance the political interests of their nations.
