There are propably a few contractual issues, but perhaps he could release the concert version as the "music video." It's been done repeatedly of late. John Legend has the concert version of "So High" out in addition to the original music video and Alicia Keyes has the concert version of "Unbreakable" out in addition to her original music video. In this case, Will would only have the concert version, but it would be better than nothing. His people may have to renegotiate Mary J's pay since the video would be released, and go from there.
