If you're really clever, you could put the gearbox on a fourth jack shaft between wheels, and reverse the mounting so that the mounting bolts are accessible, and the gearbox slides off the shaft outward from the frame, same as the wheels. That would be amazing!

It's certainly doable, but it's not nearly as trivial as simply bolting the gearbox in place as is done in an ordinary WCD (you have to leave space for the second bearing and whatever hex bore coupler you're using as an output).
