Those slopes would go a lot farther back, depending on how long the robot is and where the CG is. The initial approach would actually have a better aperture, since you're on your front wheels and rear wheels, and thus at a shallower angle. Then the aperture would shrink down to whatever that minimum amount is, until your CG (or something else) tilts you down to horizontal again.
Coming from the backside is even worse. If you're not flat before you get to that bar, you're going to have to be something like 3" shorter yet. so that end of your robot will have to be 11" or maybe even 10".
The real answer to all this, of course, is to make up an inventor sketch of a side view of the low bar and your chassis and layout. And then run your chassis through with wheels tangent to the correct surfaces, and see what happens.
