Also, the rule (R21) says, "plywood or solid, robust wood". If you're worried about breaking the wood backing you could use something like, oh say, solid ash. The "structural element" supporting the bumpers doesn't need to be nearly as robust if you manifest that strength and stiffness in the bumpers. Many teams actually rely on the bumpers to enhance the strength of their overall robot, because there is effectively free weight to be had in the bumpers which could be and has been played off as "attachment features"
