Yeah but then the turbo fan is blocking the air intake at high speeds. plus the exhaust of a turbo fan is subsonic, whereas a scramjet intake needs hypersonic intake.
the way to do it is either a) have a short-lived rocket engine to take you to the threshold speed, or b) bootstrap the aircraft using separate turbofan, ramjet and finally scramjet engines.
