Also, if you are going to be running chain, are you planning on #25? We learned the hard way that it might not be strong enough for flying over defenses, flat out shattering a few links. We know "flying" over them is probably not best for any drivetrain, it'll inevitably happen a few times even if drivers are careful, but if a drivetrain can't handle that, there's going to be failures.
We've done the WCD, riveted chassis, and chain-in-tube before. With this, I'd probably just resign to putting the chains on the wheel side. Big sprockets means chain will be dragging on the defenses, which is definitely not what you want. However, with chain-in-tube, if something goes wrong, it's a nightmare to fix.
