I stand to be corrected, but I doubt it. The Harrier forward nozzles use LP air whereas the F-35 uses a fan driven by a shaft. So anything affecting the thrust of the Harrier forward nozzles would probably be affecting the whole power unit. The F-35 could have front lift fan failure modes that still allow the deflected exhaust to produce significant thrust. My take on a simple understanding of the two power systems.
