Don't know how the fibreglass fillers would go. I think there would be issues with effectiveness due to their small size, plus I'd be worried about the kind of rubbing/bumping they would get and eventual fibre release.
If you could make relatively deep shelves and leave a 4" air space next to the wall, follow that with a 3" or 4" thick layer of fibreglass that spans the width and height of the shelf space, then leave an inch or so—use a low wooden spacer on the shelf or something similar—and then have the books you would have the effectiveness of a large fibreglass trap spaced off the wall and disguised by the books.
Probably even better if there are no shelves there at present is simply to run fibreglass floor to ceiling with the space behind it, and then install the shelves with a gap between the shelves and fibreglass and a lip at the back of the shelf to prevent books being pushed back in contact with the fibreglass. You'll still need to wrap the fibreglass but that gives you a pretty standard panel trap construction hidden by your shelves.
The books will still introduce some colouration but as I said, it should be minor.
