Provided you key them somehow, this also a viable solution.

In any case, the gearboxes themselves look good. I like symmetry in design a lot and most gearboxes seem to be asymmetrical.

I thought about this... not sure what we'll end up doing about it.

I also can't figure out where the chains are supposed to go. I should probably go take a look at your model again.

The middle wheel will have two sprockets on the sides of the wheel, which will run chain to the other wheels. See here: http://www.chiefdelphi.com/media/photos/26243

I bought 14T gears from Motion Industries. I also bought an 8mm reamer and a 2mm broach set to modify them to the CIM.
