Hi-- The University of Oklahoma was awarded a Grammy Foundation grant in 2013 to preserve and digitize organ rolls. I'm not sure what became of the project since the American Organ Institute there has recently been dismantled, but there's an old press release about it here:
The other group I'd recommend consulting about music roll digitization is Stanford, which was looking into digitization methods for their many thousands of piano rolls.
I hope that's helpful,
