I noticed that the drive chain will have to run from the center gearbox all the way to the corner so that it isn't on the pivoting sprocket (with a changing C-C distance). But if it does that, then the chain goes through the pivoting sprocket. You might want to make the pivot point the sprocket that's closer to the chassis to avoid this issue.

This is actually a chain in tube chassis, the chain run is identical to our chassis without the modules on it.

I really like this approach on how to make a WCD Butterfly drive!
