Printing colour naegatives as B&W's is a fairly common, generally using varible contrast rc paper & filters. Generally it is (was so common that Ilford, Kodak, etc produced filter packs for enlargers.
You are absolutely right, the reproduce as b&w well, also scanning as b&w function for a digital file can be reproduced with inkjets using shades of grey instead of colour. You can have a b&w printed on color paper but they tend to be cyan rather than black (or some shade of grey).
The distinction between b&w negatives and colour is an intricate point that many fail to grasp. B&W has a greater latitude => 8 stops of light while colour negative has only 4 stops of light between pure black and pure white [pure => point at which detail (texture) is
losed]. The b&w range is greater than the colour spectrum of colour film which is the major difference between these two film types, slide or positive film has a rather limited range of 1 stop of light.
Aything above (greater ev) becomes clear, anything with a value of less than goes to pure black [lacks detail].
