I don't see any reason that rack wont work. Blackburn racks are pretty bombproof. That said give it a solid looking over. I would remove it from the bike and closely check each weld for any cracks. Assuming your rack connects to the frame above the brake boss like the one in the photo it should be plenty solid. Its the side to side motion that causes racks to fail with panniers on them. Also I would measure the width of the panniers hook to hook and be sure they will fit on the rack and still provide good heel clearance for you.
