Printing stochastic on newsprint paper stock is way out of limitations imposed by this kind of paper.
For one, you have to register very fine fixed size dots (of approx. 2% equivalent percentage at 150 lpi apparent AM resolution)
Second, dot gain on newsprint is way too much (typical SWOP 0f 20% expected, may go well over 30%).
Third, FM (stochastic) rasters inherently suffer from noise in the highlights areas and this is further pronounced by high dot gain.

So if you have some good results we certainly would like to know details - kind of press used, kind of paper stock, heatset/coldset workflow e.tc.

PS To answer your question, I don't know of anyone doing it on newspapers
