This sounds like something that could be done in Inkscape. Import the scan, and do a Path->Trace Bitmap operation, which will get you a set of paths. Then, select the paths for the holes, and do a Path->Inset (or Path->Linked offset). Import the two sets of paths into Blender, offset per the height of the fascia, and loft between the two.

Hmm... never mind... I just tried it out, and it doesn't work well. There are too many shadows in the scan that confuses it. The yellow is the scanned vector, overlayed with some alpha on top of the original image. You can see it does a fantastic job around the edges where there are no shadows, but you're still left with a lot of cleanup work. :-p
