Living Lines Graphics

I am wanting to look into using a Living Lines Style graphics for a side scroller for Unity. Would making the model and drawing it out on the UV map achieve a similar effect? Is there a way to do an inverted Toon shader that would be lighter on the edges instead of darker? Or maybe something similar to Photoshop’s “Edge Effect”? A lot of questions, I am just curious, I watched Glen Keane’s “The Duet” and realized it would make a beautiful side scroller style.

If you haven’t seen Glen Keane’s “The Duet”, here is the link.
