I would recommend moving the flange from the bellypan to the clamshell. That is what we do and works marvelously. It makes it so that the brake doesn't need to be the correct length for the front and back of the bot.
Also, consider adding some ribs inside your clamshell. That will add quite a bit of strength. Take a look at how we do our frame. There should be pictures available somewhere online. I expect to only make small modifications to it next year, assuming that the game cooperates.
What machines do you have available to cut out those parts? That will require a lot of laser time if the bellypan is being laser cut, and is a pain to punch if it is going to be punched due to the triangles. Some small changes should make it a lot easier on your sponsors.
Consider integrating your battery box into the frame. There should be some pictures of how 971 does it somewhere, or you can read my suggestion in Madison's thread.

Since it's all dead axles does the clamshell really need ribs? Don't the bolts and spacer act as ribs? Also how would you go about getting wheels in and out of the robot in your configuration? The current system has them drop out the bottom very easily. Also when I said it couldn't be assembled I was talking more about getting the wheel and gear assemblies into place not just attaching the sheet metal.
We do it all on a laser cutter, but it's run after work hours so they aren't that worried about laser time. They don't have a turret punch so it doesn't really help to make them circles, the laser is doing all the work either way.
The battery in this robot will end up lying flat, I'm also not a big fan of the battery on either bumper rail. If our design ever needs that much weight shifted to one side of the robot we would probably do it but it has never fit our design.
