If PW can get it to work providing significantly lower noise and use say 10% less fuel then the newest CF34 and CFM56's there will be interest by Boeing, Airbus, Embraer or a combination of those..
The large cross section of high BPR engines will probably force them up from under the wings. The tail, wings and fuselage could play a role in further reducing noise exposure.
