Not really doable. Printers will struggle to create something with enough range to meaningfully test modern digital cinema cameras, and linearity issues make it very difficult to achieve any sort of accuracy.
Bear in mind, if you want a 15-stop chart, and in reality you probably want a bit more than a 15-stop chart, the density range is 215 or over 32,000:1 (which is why it is difficult to make high dynamic range cameras.)
At that point it is very, very difficult to create a blacker black or a whiter white, to the point where charts like that tend to be backlit and use "cavity black" where the darkest chip is actually a cutout box lined with black velvet (or you could find some vantablack paint, it does exist). The best approach is probably to get some ND gel, hope it's reasonably accurate (you can measure it, of course), and start layering it up on a lightbox. Done carefully with the right values you can avoid having to use more than four layers, and avoid having the error in the gel add up too much.
You will have noticed that DSC Labs' Xyla backlit chart is extremely expensive. Note the chips reduce in size as they get brighter to avoid the inevitable small veiling that all lenses have from making the darkest chips invisible in the glow from the brightest ones. There's also a sliding window that allows a small range to be visualised all at once.
The actual physics involved in dynamic range in the modern world of thirteen or fourteen stop cameras is becoming quite extreme, which makes this difficult.
