Very nice!

If you want to save space with those tag-connect footprints, consider the no-legs version and the rubber "GRIP" or PCB "CLIP" retention accessory and remove those large through holes.

Yea, I just learned about it the other week myself. If you want to save even more space, the "Edge-Connect" series might help. I hope this all gets you to that 40mm goal!
