TL;DR -- or, to sum it all up:
I think the problem is less about Meredith and Orsino, and more about PC Hawke's class and suriving sibling. A mage Hawke is more likely to side with the mages, because they are a mage; regardless of Carver's influence who antagonizes you despite being family. And on the other side of the coin, a non-mage Hawke is still more likely to side with the mages, because their sweet and innocent little sister is a mage, not to mention that their father was a mage. So, short of giving you the option of keeping both of them, or allowing a decision in game to dictate which sibling survives in the prolouge, I think the only way to make the endgame decision more "grey" is to allow the option to not pick sides before facing the final boss fights.
I did actually unfortunately forget about Bethany in the OP and that was wrong because she was a major factor in my choice.
But Bethany isn't a factor in every game. The impact will be less if she's a Grey Warden or dead, which is the case in many games.
I think the problem with Meredith's decision is that the game was asking players to make a mostly ethical decision, so if the Right can be justified by some other value it won't won't hold as much weight with the player. Besides, Meredith's reasons also ring hollow to me because one of the purposes of the Templar Order is obstinately to protect innocent mages from bloodthirsty mobs. So if they demand blood from an innocenet party, then the Templars Duty is to protect them, not cave in. Meredith never seemed concerned about the mob when it was against her policies.
