Obviously, orthodoxy does not matter if Anglicanism has no distinctives at all, just the local church affirming the Creed.
Your view about Orthodoxy is different than mine.

Peter E. Gillquist - Wikipedia, the free encyclopedia
Peter Gillquist is the current leader of missions of the Antiochian Orthodox Church USA. He and 6 other leaders of Campus Crusade for Christ spent a couple of decades seaching, formed a seprate church body, and eventually brought most of those in his churches to Orthodoxy when the Patriarch welcomed them with open arms.
Saint Tinkhon came close to concecrating an Anglican bishop to be a bsihop in the Orthodox Church. Their worship would used the Anglican Book of Common Prayer.
These two examples are of Western churches being accepted as Orthodox.
There is only one holy, catholic, and apostolic church. I think it fine to believe that there are branches of the one true Church. I believe that to be true.
However, I believe that it is an accident of history that Archbishop of Cantebury is not the Patriarch of the Anglican Orthodox Church. If Rome would reject supremacy of Peter in favor of primacy of Peter, and sit down in Council, the Patriarch of Rome might be accepted by many.
================================
The Orthodox option is an interesting one for Anglican churches. ACNA may in end choose to accept the authority of OCA. They probably will not any time soon. Others may choose to follow many of the Crusade for Christ in their path toward the Antiochian Orthodox Church.
Or ACNA and other outsiders may decide to accept second class membership within the Anglican Communion, or the Communion might divide into parts.
Orthodoxy is one option within the universal Church. It is certainly not the only one. However, I do take a different view from yours. While I agree that Met. Jonah (and the other metropolitans) want to add numbers to their existing churches, there may an opportunity for whole church to come into orthodoxy and keep much of their American heritage, as Peter Gillcrest has done. Peter Gillcrest is not a priest in a Greek Church or a Russian Church, a Roman Church or even an English Church. He is a priest in an American Church which is part of the universal church.

But regarding Met. Jonah of the OCA, I'm a former OCA Christian and I'm a bit perplexed why Anglicans care what Met. Jonah has to say about Anglicanism? After all, unity with Orthodoxy means to Orthodox Christians that you become Orthodox Christians. They might allow you a quick catechizing period and possibly even to worship with some sort of "Western Rite" (though only the Antiochians and ROCOR currently have Western Rites), but otherwise "unity" to the Orthodox simply means "join us." Any serious "dialogue" with Anglicans is always done with the hope that they might poach some sheep and by Met. Jonah's own admission, they're quite good at that (as he said in a sermon once). I don't say this to be rude or overly critical of Orthodoxy, but the bottom line is that they will demand Anglicans to accept all Orthodox doctrine before allowing communion with them, which basically means that you become Eastern Orthodox or maybe, Western Rite Orthodox. Of course if one wants to become Orthodox, that's another story. But I just don't understand what Anglicans think they'll achieve with dialogue with the Orthodox or why anyone would care what the Orthodox think of Anglicans. It's pretty much a become Orthodox or not scenario as far as the Orthodox are concerned.
