I don't think so, as you can't build an L shape with 'polygon type.

Yes, the (hint-wire) lines are drawn with some offset so they don't
intersect with the solid geometry of the object they belong to. The
ribbons just get splatted in the middle of this - notice the line inside
the corner of the L shape is not always visible? That's a problem with
this approach.

Who knew wireframe could be so hard! :)
