So could we all. But I suspect that the general lines of development will not be dissimilar to your estimate. The only issue is within the Anglo-Catholic stream. It is possible that certain lines of descent in that group will wither because some of the purposes for separation were not necessarily fully worthy. To the extent that any Anglo-Catholic communion keeps her ecclesial, liturgical and doctrinal eyes fixed on her Founder to the exclusion of all other purposes and intents, that communion will thrive.
As for union with Rome, my own preference would be autocephalous standing under a Patriarch with real authority to enforce doctrinal discipline. The issues of certain Marian and treasury of the saints doctrines would likely keep this communion chary of participating in Councils where RCC votes could simply carry the convocation by majoritarian weight of delegates. The issue there must certain refer to the degree of independent episcopal authority bishops subject to Rome would bring as delegates. To the extent that they MUST vote as Rome directs, to that very degree Rome should have rather limited participation by numbers. Perhaps a supra-House of Bishops would come into consideration, to reflect co-equality of Patriarchs rather than weight of bishoprics.
All very speculative and non-substantive, of course.

I quite concur with your highly-educated guesses, Deacon Paul. *\;-)
Deacon Paul,
It is interesting to note that when there are actual councils of the Church, they do not operate by majority voting. What happens is something more akin to the Quaker concept of the "covered meeting". While there are, no doubt, politics involved, the issues have not historically been resolved by brutal up and down votes with first-past-the-post majoritarian logic. Something more gentle takes place.
An Anglican patriarchate in full communion with Rome would be a good solution. Why not? English is by now an ancient liturgical language. Let it be just so. The political fears are probably unjustified, but let the Anglicans discover that for themselves. There is a special prelate for Opus Dei. Certainly there can be a unique role for the returned Anglican house. 500 years has made a difference. I don't think it should be enough to keep the Church divided, but it should be enough for special care and love and consideration.
Likewise for the returning Lutherans.
With the Orthodox, the patriarchate is already a given.
