I've finished a play with a, as you put it, board and sword Human Noble. He ended up sharing sheets with Zhevran, since Morrigan doesn't like the knight in shining armor type, and I Leilana was at the "Lets just be friends" point of a relationship. And yes, it is very fun. I'm currently running through with a slashy-stabby Dwarf Commoner Rouge.
As for the issue with Leilana, if you update the 1.0.2 patch, it's a lot easier to do her personal quest and get her to join you for a roll in the hay. They've set it up so you can do it no matter how friendly you get with her.
