Well, you're in luck! We do indeed have an actual bonafide (and boneable amiright) Qunari on the team! His name's the Iron Bull. There's a fan thread in this subforum if you're interested in his character (dude seems really cool, and I can't wait to get him in the party).
I'm... not entirely certain what you mean about Kaiden 2.0, however. I've never done that romance, so, uh, could you perhaps explain? 
Iron Bull was formerly of the Qun.
Not quite the same as currently of the Qun.
Also why do characters that we know little about have fan threads?
I get fan threads for characters in released games, but unreleased games?
Don't get me wrong. Freddy Prinze Junior is a fantastic actor. His charm made those tiresome 90's rom-coms bearable.
His James Vega was an awesome addition to Shepard's crew.
This Iron Bull character sounds promising. Really promising. He could be an awesome character.
However I don't really know if Iron Bull will live up to the hype. He could be bland and disappointing.
Too early for a fan thread I say.
At least with Cullen we've seen him and interacted with him in two games.
But that's just me.
