As long as only "soft" components (pool noodle and fabric covering) are used in the half-height extension into the corners, I believe that design satisfies the requirement to protect the corners. But I'm not sure the 5" bumper height rule can be interpreted to permit it.

I'm curious why you'd want to do it that way, though. It seems an unnecessarily complicated shape, and it strikes me as likely to have problems with the narrow bits of bumper getting bent and going outside the bumper zone in normal gameplay.
