Joe,
That's the strangest "take" on the filioque I've ever heard. Imagine, a "special weapon" dogma (you would say doctrine) that can split a church for over a thousand years, and then be withdrawn quite easily at any point... and it all depends on how close the Church is to slipping into an ancient heresy!
Nik,
FWIW--and I certainly don't think my experience is extensive--I've found that the Pope Honorius issue (like 99% of the other arguments in this debate) ultimately only leads to a stalemate. It's that way with everything. Filioque/purgatory/other dogmas (are they "innovations"?). Church Fathers on the place of Peter. It all seems to go back and forth. Both sides can give examples for what they believe. I've found that the best thing is just to give historical example from the saints (e.g., How did St. Justinian treat the Popes? How did the East respond when the Pope rejected part of the 2nd Ecumenical Council? How did Gregory the Theologian and others (Basil, Gregory of Nyssa, etc.) respond when the Pope of Rome (with the Pope of Alexandria to boot!) fought against Meletios--not to mention how the Pope of Rome was certainly no friend of Gregory the Theologian himself at that time?) People could sit here and exchange proof texts all day... so unless you have something important at issue... um, well I don't see the point. Anyway, there's some unasked-for thoughts
