The Freestyle tools in Blender offer much more control over line tracing. However, they are not very compatible with the wireframe object currently used to display the bounding box.
For an attractive tracing setup:
enable Freestyle (SCENE.render.use_freestyle)
Setup two Freestyle line sets (one is created by default)
Atom outlines, using 'Silhouette' and 'Border' edge types and a thin (3pt) black line
Bounding box, using 'Edge Mark' edge type, round caps and a thicker (5pt) line
Bounding box line set should be above atom outlines
Make bounding box tracable
Instead of wireframe, use a regular solid material for bounding box
Create thin wireframe with wireframe modifier and apply to create new mesh
Select all edges of wireframe mesh and add Freestyle edge marks
The result of this is that the bounding box is stroked twice, with the thicker box line settings hiding the thin outline. Atoms are stroked once, with a configurable line thickness and colour.
