so have a completely separate standard. call it EOMA-136.
use a double height card and have two connectors (for which existing 
slot hardware already exists). the casework would be custom but 
constructing the card would not be difficult with two pcbs with 68-pin 
connectors bolted together with the correct spacing. could use a pin and 
socket arrangement to join them electrically.

double the pins and double the pcb real estate.

sometimes one size does not fit all
