Careful on your hinges idea. There have been a couple of recent Q&As that state that bumpers must remain in the same vertical orientation they started in, throughout the match. That's relative to the robot, of course, but it means you can't hinge the tops of your bumpers so they'll flip up slightly out of the way when you hit the ramp.
I suspect your only option for using a full set of bumpers this year is to have a 6-wheel drive chassis or something that gets your effective wheelbase as small as possible
