FCI makes a rectangular connector with dimensions that, when fitted male to female, fit the 6mm between boards perfectly. The Harwins were 1/2 a millimeter off which works but a gap is visible.

FCI on first (top) layer, Harwin on second...

Will be looking at the LC situation of lines running through the connectors soon. 100khz I2C was functional with 8.2k pullups (the top board has a bunch of environmental sensors), but I haven't hooked anything up to the scope yet.
