I love the simplicity of this design. I too would suggest that the wood be made from plywood.
Another suggestion... if you make the 4 interior wheels have a slightly bigger diameter, that will work too. What I would do is put treads on the 4 interior wheels so that they have a diameter that is 0.2" larger than the outside wheels. This may be easier than varying axle heights.
