Thanks for the insight, I'll look at that approach.

I might have missed this in the earlier conversation, but why not
explore the option suggest of using the layer's edit buffer? I believe
this should automatically handle all the reassignment without any
changes needed (except flipping the direct dataProvider use to the
editBuffer).
Possibly it's nicer for users anyway if the fixes made by the plugin
are buffered and undo-able.
The problem is that if one of the changes to be committed is refused by
the provider, you're stuck not being able to commit the entire set of
changes. And, since we are dealing with invalid geometries, it is not
that unlikely that this occurs. Committing directly to the provider
ensures that we know immediately whether a change is valid or not.
