Josh, Castellation was easy but I am not going to verify it buy buying it and building a board. I have shared a design now on Oshpark that should be correct for castellation. Other changes would have been more time consuming. I agree that the sanding thing takes a lot of effort. I used power tools to solve this, but this is a good improvement. You can try this PCB but no guarantees. Steve
