There is a way,
that I've found to do this.
These are the 4 steps that can be used.

* * *

1. Duplcate image 2 times.

2. Top image: Reduce saturation to -100,
Set layer mode to saturation.

3. Middle Image: Set layer mode to dodge.
Invert color, Gaussian Blur image (image size determins the amount of blur)
More for large image and less for small images.

4. Bottom Layer: Adjust color levers to the desired levels.

Here is another approach using Tin Tran's python plug-in 'Picture to Line Art'.

Wallace, thanks for your workflow. The attached adds a color pencil effect by reducing the saturation layer opacity to zero.
