This would be an easy design. 4" dia steel pipe set center of defense plate, with 1"-4" underneath (make it adjustable (1" increments) so the head ref pulls a number out of a hat for each time it's used)(or make it perm to the field like the low bar and set the height to pneumatics so the FTC can change randomly during a match). The end of the pipe would have end caps with bearing in them for it to rotate on (make it more fun, have the bearings off center so it has a cam effect).
