do you can add some features for VRayEdgesTex? like BLUR and possibility set-up Thickness more than 1000 (like 1000000).
and last wish: corrected corner in sharp angles.
after that will VRayEdgesTex really applicable like mask for blend material, etc.
Either with VRay Textures or in VRay Toon (or possibly both) the ability to extend the intersections. This is a common technique used in architectural illustration. Thanks.
