That outside pic looks pretty good. Taking the flat black to the outer edges of the real vent openings puts it in ‘viable’ territory. Everything is in the same visual plane now.

I just checked an eBay listing for these vents. It seems they are fiberglass. I work mostly with hot molded plastics and catalyst urethanes so I can’t be of much help regarding making the cutouts. You’ll need a precision tool to make the tight rear V cuts for sure. Variable speed dremel with a good cutting wheel? Not much material there for the lower vane. Maybe leave a mm or so of material on each side of the vane mold??

Good luck if you decide to give it a go!
