I have not personally, but the subject has come up from time to time. Part of the drawback to aging a bone in sub-primal is the need to introduce some foreign material such as a paper towel to prevent the exposed bone from puncturing the Drybag. The other issue is cutting the chunk-o-cow with the bone in as most homeowners are not up to that task. It has also been pointed out that in the large commercial aging centers they leave the bone on during the aging to control the process so as to limit the trimming loss, but then saw the bone off. Hope this helps.
