Speaking from professional experience, it is much more likely that such program would have a quite different name.
I remember buying an "F-19" model as a teen (the aircraft also showed up in a wargame that I bought). But the real program at Tenopah turned out to be the F-117--which looks entirely different. And frankly, the F-117 should have been called "A-117" given its actual combat role.
Reminds me in my model building days I had a model of an SR-71 which included sidewinder air-to-air missiles deployed from small missile bays under the belly. One can't imagine an SR-71 engaging in air-to-air combat.
