I would not recommend this. Having seams going two directions is more difficult on the longarm quilter to make it quilt evenly. Most quilts are loaded with the backing seam parallel to the bars. A seam in the other direction will not stretch as much as the unseamed edges, resulting in puckers on the back. Ideally, a backing should have no more than one seam. Really ideally, backings should be wide fabrics with no seams. You might look at Christian Lane Quilters for their 'fatbacks'. They often have sales and sometimes their clearance end of bolts are plenty.
