I just measured the chrome roof racks on my '07 HHR.
Looks like a set of these would be perfect on the bed cover of an SSR.
They could be mounted parallel and run straight toward the back.
Might have to get stronger struts because of added weight, though.
They could be mounted outside the bed cover on the edges of the bed, but they will be angled in at the rear following the shape of the bed.
There are probably other kinds of roof racks that would fit even better.
Just a thought ........
