Don't know if this would be something you would want to pursue or not, but go to RealOEM.com parts site, get into the lighting chapter, which is chapter 63, under auxiliary lights, fog lights, they show a mount, they call it a 'bow' that you can attach two headlights to , it looks like it bolts to the sheet metal mount for the headlight .
Don't think the part is available anymore, but just to give you an idea what can be done .
