 I'm not sure if Arthur's decision at the Disir would have changed his destiny either.

I'd say that it would have. Morgana is High Priestess of the Triple Goddess so, if the Triple Goddess was satisfied with Arthur's amends, She could have ordered Morgana to cease her aggression towards Arthur and Camelot. If Morgana refused to obey, she'd be the one hauled in front of the Disir.
