You could probably make this work without a convex bumper. You could make the robot a triangle, with two gaps in the "front" bumper. You park on the center batter, and when a robot approaches a low goal you rotate slightly to push the gap intake that corner of the tower.

Since you have to rotate to block, two offensive robots working together could slip a ball past you on the other side, but you would still reduce the number of goals significantly.

I love this effort though. Evolving strategies and robots keeps FRC interesting over the competition season.
