I think you are headed in the right direction with the euro parts. However, the other parts clash. I would ditch the konig's, billet grille, and possibly the headlights. I would look for a euro front grille, black svt/euro headlights. I think the sidestripe coming out of the fender vent was a good idea but it really clashes with your body lines.
