If the conspiracy people really want to prove that the towers should have withstood the attacks, then they could build two towers exactly like the WTC ones, fill them with similar things as the orginials, get two large planes filled with jet fuel, with remote piloting, and make them crash into the buildings exactly like it happened on 9/11. Half a million tons of debris from 9/11, and theories from engineers and amateurs alike, are not going to show nearly as much as an experiment such as this could.

If they collapse, then MORE conspiracy theories would start - about the experiment itself.
