Otherwise it seems like a very versatile platform, good stuff.

Let me see, the chassis design #2 was about 16 lbs, on the heavery side. However, the pods weight an estimated 40 lbs total with everything on them and no lightening holes, way too much. Add battery and air compressor, and your sitting on something around 70 lbs, very heavy.
As to the #3 and #4 gearbox my teamate just whipped those up to better clarify what it could look like. The middle gear would still rotate around one of the other two despite not being it not being pictured. And It would require only one small pneumatic cylender to move it back and fourth 1/4 of an inch.
Other things you might find interesting. the mec wheels (entire pods actully) will be on a three degree angle when in mecanum mode, and rotating them about 31-33 degrees gets the pod cleanly above the plane of the frame so as to bottom out. Just fyi
