In that vein, I'm using this system for duping B&W negs. With my Nikon D300, a transparency is right at the boundary of it's dynamic range, but a more modern camera would give me a couple of more stops of range, and I think it would work fine. I do so much of this, I'm thinking of getting a Sony NEX-7 to plug into this setup:

Of course, that's film to digital, which isn't going to get you another slide.
I used to produce educational slide shows and film strips, and did my own slide dupes using Kodak's E4 duping film of the time. They didn't look like the originals (the problem wasn't contrast. . . it was more like a saturation issue, if I remember right), but honestly, the intended audience wasn't going to know the difference.

camera setup usually consists of a unit having a camerabody and lens, bellows extension, light source, acopyboard, filter holders, and the necessary controls andswitches. When slides are copied with a slideduplicating camera, the slide is transilluminated. This isthe most common method of copying slides.corporate gifting ideas

I used to make dupes, normally with this dupe film:

We used to use a DeVere Dichrocopy which was a kind of upside down enlarger with a camera mount.
I can honestly say that reproduction dupes were pretty much identical to the originals so much so that even with a schnieder lupe 99% of people couldn't tell the difference.
It was common practice for photographers especially those using large format to send out dupes to stock houses rather than originals.
I also owned an Agfa film writer in the early-mid 1990's we could make copies from digital artwork on slide film or colour negatives, you didn't need dupe film for these machines we used Ektachrome 64 and Ektar 25 (neg) in other words ordinary daylight film.
