You should probably ask the Q&A exactly that (or build a conventional set of bumpers, in case the inspectors rule it was a global constraint).

*In what orientation?

Q&A has already ruled that angled bumpers and bumpers at varying heights are legal.

Game - The Robot » Bumper Rules » R29
Q. As long as no other rules are violated, can the various sections of bumpers on a robot be at different heights within the bumper zone? Would this apply to the 2 bumper sections on adjacent sides of a common vertex? Can bumper sections be mounted non-parallel to the floor in the bumper zone? A. There are no rules prohibiting either of these scenarios.

If it's total height of bumper plywood, then the quoted Q&A needs revision.
