In some sense (with the warning it is currently incorrect, I'm working on a new improved version) you can see how I'm doing it in my post in beginners:
the worst error is the advise to save as optimized svg, turns out that breaks gerber production. In fact you should use plain svg as recommended (but you have to post process if using Inkscape). In any case I have a test version of what I think your device should look like. Please try it out and point out errors in pin numbering or
placement on any view and we will see if I understood what you told me (I have some doubts that I did 
).
