If you left your manipulator down in that position all match long, you might have a valid argument for extending the bumper as shown. But I presume you intend to move the manipulator at some time. Then the leading edge of the frame defines your bumper zone. Once you move the defining edge of your robot, the bumpers have to be in compliance with that new edge. There was already a Q&A for the opposite situation - someone wanted to know how to measure 2/3's if the frame size expanded after start, and the answer was that 2/3's applied during the entire match. I would imagine the GDC would make a parallel ruling for your robot, that the bumper could not extend past the corner of the frame once you moved your mechanism.
