If I understand correctly you want to generate this:

This can be done with a LineOnLineOverlayer and a LineCombiner, see attached workspace.

Hopefully this works as expected.

igds2none.fmwt (FME 2017.1.2.1)

The boundary lines of input areas can be transformed into a network edges, and the priority of each edge is determined by one of two (left and right) layers. So, duplicate each edge into two for left area and right area, merge layer name and priority from area to the edges, keep one having higher priority, then connect them grouping by original Layer name.

I thought that the layer names in your dataset represent priorities. How would you like to determine the priorities based on the layter names?

Somehow I'm not able to download the workspace. Might be something with the design of the new community pages? Is it possible to share the prioritytrim workspace again? Thanks!
