Keep refining this until it is 100% ready for production, it will save your team a lot of time.

It might save time.
This would be a possibility, but a significant change to my current design. But part of me wants to try using the extra stage. If it works it could be great. Using a chain reduction would a significant amount of weight and space.

I'm not a big time drivetrain guy... but can a DeWalt transmission take the torque of two CIM motors? Perhaps you could combine their torque before going in to the transmission?

The DeWalts would almost certainly be strong enough. But it would give up these advantages of my current design:
-weight balance of CIMS
-if any chain were to break, only one wheel would lose power
-does not require an extra gearbox to gear the 2 cims together

dbell - are you planning on keeping the clutches? If so, you should read this: http://www.chiefdelphi.com/media/papers/1680. They kept the clutch in and found that it bent after a couple of matches, causing them to service the transmission frequently. If you aren't going to keep them, how are you going to keep the first ring gear in place?

I am not planning on using the clutches. I'm not sure what you mean by "how are you going to keep the first ring gear in place?"
