Without cutting the traces, they may ripp off the board on the 'inner'-side of the breaking. But I think the good news of the thickness of the board is that keeping two break off spots at the USB end should be strong enough to hold on to the PICO - for placement and soldering. Milling first the two long edges incl the USB sides, and then the USB tip, then drilling the holes in the breakout parts at the left and right side of USB tip... No problem w/ Jaltek the specialists, but listen to ideas never hurts... it's difficult though ;-)
