They couldn't even meet for a one week council our of fear of having to go through a Vatican 2 style revolution/reformation, how on Earth would anyone imagine a desire to unite with Catholicism in its current liturgical state.  The Orthodox liturgy have changed very little, they simply cannot recognize the new Roman rite. The only chance for reunion is if we get closer to each other, either by them also going through a reformation/revolution or us rolling back all the changes that do not have origin beyond the 60's.

Even then it may not be enough, I can't imagine them accepting either of the Vatican councils without them being defined as local councils for the Roman rite exclusively.

Even then why should they, look at the fruits of the change in the dominant RC countries, the importance of Christian faith is decimated compared to the East, where only Poland is the exception.
