Rafe: About five years ago, Leif/Scitex started selling their Lumina camera which is what you are looking for. It takes Nikon lenses, is a scanning camera with 2700 dpi sensor. Yields files about 26 meg in size. Has through the lense viewing. However, it must be tethered to a computer. Depending on lighting, scans take from as little as a minute on up. It has a D-max range of 3.0 I bought it when it first came out for about $6,000. Used it primarily as a multi-format transparency scanner. Also did occasional studio shots with it. Today I use it for some direct scanning of paintings for reproduction purposes. It still does a reasonably good job, but technology has advanced in terms of scanning chips. I wish that I could just plug a new, higher resolution chip in. Scitex was hoping to sell a lot of these cameras, but they didn't seem to have the proper marketing to do it right. I bet if you did some snooping you could probably buy a used Lumina for that $2,000 you are looking to spend. They came with PC and Mac PhotoShop plug-ins. Regarding taking a cheap flat-bed scanner and trying to make a camera out of it--good luck! Being a EE you should realize, it ain't that simple. If it were, some "pin-head" ;-) would be bragging about it on many lists by now. Sort of like the "bulk ink" delivery systems for the small Epson printers.
