Eh. Maybe. They haven't developed a clean sheet supersonic turbofan since the 80's. This Boom "Overture" thing is going to need an entirely new design for long duration super-cruise; Boom needs engine people with a lot of depth.
Safran's M88 should be sufficient for Boom's 1/3rd scale demonstrator I think? Then at least they'd have something to show other manufacturers and investors.
