Is it possible to combine a toon shader with a standard shader in Maya?

[emartin3]

I have an object I have shaded with a standard shader. Now all I want to do is add a toon edge to the existing shader. I've tried aiMix with multiply (the toon is solid white via emission so I was hopeful only the edge would show up). No dice. I've tried aiLayer and aiComposite. Seems like the input of the surface shader RGBA doesn't work with how I've tried combining the two. I know I can composite a flat white toon shader with the shaded item if I render them as separate layers and composite in post but I'm wondering if there is a way to get an edge to a standard surface?

You can mix toon edges with standard:

Yes I can blend the two but unfortunately I want to multiply. Blending blends the toon shade base color over the standard shader. I want 100% of my standard shader with just a toon line. Any idea how I remove the other components of the toon shader?
