Yeah I'm currently on my first playthrough as Lord of Fortune, and would love to explore that background a lot more in quests, or even in just more conversations with the relevant characters.
....although regarding the lyrium idol, I think it's implied that Solas used parts of Mythal's soul fragments to get his "god" powers back, and therefore able to cleanse the idol, resulting in the dagger.
That's true! We can assume Solas was able to cleanse it with his returned godlike powers it's just been so rarely seen in games and they advertised with the red lyrium it would have been nice to see if happen.
