Hi, you may be over complicating things by using hex.if you just want to extend the wheels for transport then you can use round tube that just slides over the circumference  of the top of the hexes then drill through and use a bolt which transfers the drive..then the same for the solid part that the wheel slides on but using solid round bar..If it does not make sense to you i can try and draw a diagram.

In case I have misread,you also need a bolt through the large tube and original hex drive shaft to lock them together. as well.
