Man, those are some thick dropouts!
Since this bike is a special case, one thing to consider is just to move some axle spacers from the right side to the left and re-dish the wheel. That would put the cog in better alignment with the chainring. You would lose the ability to run the wheel as a flip-flop, but I don't know what else there is to do besides having the bottom bracket shell faced down to 68mm.
P.S. The spindle length will be the same between a 73x107 and 68x107, and I believe the spindle is symmetrical for both. So if you mounted a 68x107 on your bike, I would expect the crank to move 2.5mm further out!
