The negatives will print fine on Panalure. I am not sure
why the original poster wants to avoid Panalure. Its
conventional RC paper that is made panchromatic for correct
tone rendering from color negatives. It must be handled in
total darkness or under a color safelight (Kodak number 13)
but otherwise is processed identically to regular RC paper.
 Color films of any type can be developed to B&W negative.
D-76 works fine for this but, of course, there are no
published times, one has to find them experimentally or from
someone else who as found the times. Generally, the tone
rendition will be OK but the images are grainier than the
equivilant dye images would be.
  Color films _are_ B&W silver film with three layers of
emulsion. Each contains a substance, called a color coupler,
which, in conjunction with the reaction products of the
development of the silver image, forms the colored dyes. The
silver image is removed leaving the color dyes in place.
  The orange color of color negative films is due to the
couplers. In two of the layers the couplers are colored.
This forms a low contrast positive mask in normal color
development. The color is correct to correct for the
imperfect spectral characteristics of the image dyes. This
results in better color saturation and purity in the
resulting print.  Color reversal films do not use this
system of masking but can have other means of improving
color rendition.
 The problem with the coupler is that there is no simple
way of bleaching it without disturbing the silver image.
