Changing tack on my earlier suggestion to lace the non drive side I can now see that there is a possibility of damaging the hub that way. Some hubs, even pretty good ones like a Sunshine Gyromaster are spin welded to join the two halves at the center of the barrel. What about multi-piece press fit hubs? Also the amount of torque required to remove a freewheel is so variable.
