Hey I know it is silly, but it would give some catharsis to the story without sacrificing the central theme. You would have Werden and the Solansia Saint lady try to stand in favor of Rowan but the human nobles would have whipped the crowd up into frenzy and he'd get executed then you'd have something like the skies parting for Solansia to favour him and that would lay the grounds for a full on rebellion. It makes Rowan's path meaningful but also doesn't give him an out for all the atrocities he will have to commit to save Alexia.
I just don't want a happily ever after even in the purest version of the story.
