You know what's interesting? So far I haven't seen any fanart or fanfic of Solas and Lavellan getting married. It's like marriage makes no sense for this couple even if they were to get a happy ending. It's like their love goes beyond marriage.
I mentioned something about this a while ago. It was a simple idea for a drawing.
Panel 1 is just text: "Solas is lifting the veil"
And Panel 2 is a picture of him lifting Lavellan's wedding veil and the two of them looking stupidly adorable and lovingly at each other. 
This is beyond my skills though. >_<
