It can certainly be done, and very well at that. You have the right concept in terms of doing something up top to ensure that the darkness of the trousers doesn't draw attention solely to your lower body. There is a complicating factors, though. Everyone should dress to draw attention to their face. Simply because of the fact that you need to draw attention away from dark trousers in a northern lights fit you run the risk of drawing too much away from the face with a tie, shirt, or patterned jacket. This isn't to say that you have done that, I actually like your fit a lot. It depends on you having fairly dark hair against your light skin (a high contrast face) to balance it all out though. If you have medium or light hair (meaning that you have a medium or low contrast face) then it won't look as good.
