"...Uniatism. That's caused quite enough trouble already and, I think, Rome has rejected it, at a minimum in public"

I thought Uniatism were the Ukrainian Catholics living among the Russian Orthodox Catholics... Those living in the US are considered Uniate? Rome rejects the Eastern Catholics? I think you are mistaken. Rome has written encyclicals on the Eastern Churches - I'd have to look up the names of them. But Vatican 2 writes about them, considering them a bridge.

The term has a broader meaning than just "Greek Catholics" in the Ukraine. The much, and perhaps deservedly, maligned Balamand Declaration makes it clear that what you propose as a model for reunion is rejected by both particular churches.
