Okay...tried the lip mask, just turned the default lips for this face texture green for the alternate, added some gloss. I popped a bit of pale green in the primary diffuse color of the lacrimals, as well as keeping the original saturation on the eye map for both lacrimals and specular. And then I remembered to add my AO, which I totally forgot in the first tests.

Any input on the lacrimals, sclerae and lips?  I'm wondering if I ought to go for an even more softly feathered lip edge. I love the sclerae now but the lacrimals are still jarring me and I can't pinpoint why, unless it is just a subconscious rejection of green lacrimals.
