Neither would I. Some of the LIs mention physical traits they prefer; Sera's into qunari ladies, and Bull has a thing for redheads. Solas doesn't. It's probably the spirit that matters to him.
So if appearance is no object...krogan ladies like scars, and Solas has a few. Let's hook him up with Urdnot Bakara! She can talk sense into him, or failing that, point a Claymore shotgun at him 
AHAHAHAH I think my jaw dropped to the floor.
Bakara can definitely do better, though, I think, than some dorky fade elf 
i liked Solas because I liked his mind, I liked his intelligence and his philosophy. The fact that he's all for as much freedom as possible and opposed to slavery be it of the mind or of the body. I did not "fall in love" with him because of the Dread Wolf thing or any of that. As a fellow elf and mage, I felt kinship with him that deepened as I got to know him. He did not cross a line with me (as he later reiterated), despite what I hope was a strong temptation, and I respected that. Just as in Dragon Age II, I did not find Fenris particularly interesting until I realized how intelligent he was, I tend to like smart guys. (Or smart-a**es).
I certainly didn't see him as either Twilight's hero, or the controlling, let-me-take-over-your-life, character of 50 shades. Neither did I feel like the "Petra-Pan" character of Bella who never wanted to grow up, nor the stumbling, bumbling idiot virgin of 50 shades either.
Yeah, I think some fans often tend to overstate the darkness of his character in the romance. I mean, Solas has a perfectly nasty side to him, but you only see it during low approval scenes where your Inquisitor is often being a jerk. High-approval inquisitors see little of that - I think that's partially deliberate. You're encouraging him to become better, to do better, appealing to his sense of compassion and his wisdom, when you're on a friendship/romance path.
Solas isn't a byronic hero. His darkness doesn't come into the romance, unlike those examples you mentioned (and that's the reason why I don't like them: it's a romanticisation of something unhealthy and gross). He doesn't romanticise the uncompromising, cold part of him that can justify destroying the world - he's perfectly aware of how cruel that is. What I like about the romance in Trespasser is how it doesn't apologise for the worst parts of him, and how love still persists, but it doesn't solve the irreconcilable differences of position between the two of you.
It's kind of why I don't like dark!Solas fics. Solas is an adorkable fade nerd who is a little bit reckless and accidentally falls passionately in love with you. There's none of his Fen'Harel persona there - Fen'Harel is the reason he breaks up with you, in fact, because he doesn't want you to clash with his plans and ambitions.
