Every theory is viable until you are able to refute it. (with some limits)
Yes, and one of those limits is that the phenomena that the theory purports to explain must actually exist, and if they do, are not already explained by other better-supported theories.
I could create a theory of why the moon gets shy and hides itself every month, which you wouldn't be able to refute. (No one has expertise in the moon's feelings, so any reason I give for why the moon gets shy would be irrefutable.) But you wouldn't need to refute it; you need only show that the disappearance of the moon on a monthly cycle is already adequately explained as the expected consequence of well-understood and thoroughly documented processes affecting the relative positions of earth, moon, and sun.
Similarly, it's irrelevant whether your thermite theory is refutable or not, because it is not necessary to explain any of the phenomena it purports to explain. It's as irrelevant as Max's heat-weakening theory, Apollo20's Ammonium Perchlorate theory, and my iron-deadweights-dropped-from-high-altitude-dirigibles theory, and for the same reason. The observed phenomena are already adequately explained as the expected consequence of well-understood and thoroughly documented processes affecting a steel structure and its contents exposed to collision damage and fire.
That is why, to make it appear relevant, you had to start out with an unsupported and non-credible assertion in your very first post in this thread: that the cores of the towers were each capable of supporting six times the weight of an entire tower. To anyone with the slightest knowledge of structural engineering (or of the most basic economics of building construction), that's as silly as if I introduced my embarrassed-moon theory by first asserting that the moon doesn't actually orbit the earth, in order to make it seem like there were phenomena that my theory was needed to explain.
And that, in turn, is why once you have satisfied yourself that your unnecessary theory has survived the JREF forum's most desperate attempts to refute it, there is no next step after that. The press, the courts, academia, corporate interests, professional societies, and political organizations will all readily perceive that your theory is useless and so it's "irrefutability" is of no import. Even truthers will pay you little attention because ultimately all you're doing is repeating what other, better-known, more widely published truthers are telling you. Why get their lies second-hand from you, when they can more easily get them directly from the people making them up? You will get no hush money because hush money is only paid to someone who knows something important enough to be hushed. An unnecessary theory, unsupported by evidence, not even well-formulated enough to be refutable, doesn't come close.
