Well... the only reason i didn't make the lines a saturated colour (usually i'd agree that's what to go for) is because the celshading lines around the hair strands would still make the hair shapes stand out too much like big chunks. Making them a colour drop of the outline (which doesn't look pure black) will make it look more coherent to an observers eye
As far as the effort... well it should be pretty mininal, you could set up the UV maps (seperated via smoothing groups, pelt mapping, whatever) do that and bake off an ambient occlusion pass to help generate your shading (to match up the shading across the hair) in about 20 minutes tops. He may not use max, but i bet someone could do it fairly effortlessly for him... it'd definately make the final result better
