Jacques Favino was trained until 1946 at Busato and he had a secret to improve the tone of a guitar and its projection. I have tried it many times and it works. Put a thin layer of maple below the bridge (minimum .4 mm, maxi 1 mm thick). Shape the ends as shown. This way the thin layer of maple yields a perfect impedance between the bridge and the guitar top.

Patrick Inghilleri is a wizard who knows better than anyone to make a perfect bridge and to amplify an acoustic guitar. Look at his system in Amps & Pickups.
A lot of luthiers do not like ebony for bridge. Most like rosewood. Killy Nonis likes a nice piece of dense walnut, it gives a great warm tone.
