First try with halftone negative and gum

My first impressions are positive. The halftone pattern can easily be seen in the 12 lpi print.

Unfortunately the resolution of the emulsion is less than the resolution of the halftone screen past 12 lpi. Brushstrokes make it hare to see the pattern. That said, I think the 50 lpi halftone screen looks like is has better gradation of tones than the grayscale image (though the exposures were certainly not equal)
