Someone posted a CAD render on DAY 1 with the configuration mentioned. It's going to be a long year for the inspectors...

A legal configuration for legal bumpers includes the following relevant items:
R22: 6" on either side of a corner in the Frame Perimeter (not necessarily the robot's frame--wrap a rubber band around the frame instead of string, maybe?)
R29G: Secure attachment to Frame Perimeter

Now, the described configuration fails to meet R29G, as it's not on the Frame Perimeter, and fails to meet R22 because it's not protecting the corners of the Frame Perimeter.
