No, it still doesn't. Whether you consider your Charisma bonus to be typed or not, you still only have one.
A scaled fist monk/natures whispers oracle has two abilities allowing them to add their Cha to AC. First one adds it, second one sees it is already being added and therefore has nothing to do. Neither ability generate a second bonus, so the stacking rules are not involved.
This interaction is exactly the same in 3.5 and PF1, and both with and without the FAQ.
That said, treating it as if it did work is unlikely to break anything. Even unchained Monks are not that strong.
