I am not sure if it helps you or not but we are just now finishing up with a 3.5” x 3.5” fpga board design where we will mount a 2450 board on top.   Would love to collaborate.

Going from 36 sq-in to 18 sq-in is a big improvement for us. We'll be using it on an underwater vehicle, and space is a premium. Your idea for a smaller WBX board is cool, but would be a lot of work.

That seems like a lot of effort and expense to make something just a little bit smaller. Now, if you could make the equivalent of a USRP + WBX board about the size of a pack of playing cards, and powered from the USB port, that would be quite interesting!
