Sorry been out all night dint see the thread. I would do exactly as the CAd drawing showed. krish75 Greta idea, If its not centerd then utilize the same brakets till to trim it out>BRILLIANT!! as far as a hanging system. depending on price difference I would go to the lighting department in HD and look at Chandlier chains. The come in variety of colors and styles. If your system has what I suspect as mounting bolt to the unit, They would work, Just thought . Chandliers are heavy and those chain rated for up 80lbs. Just a thought.
