It can't be ruled out but I still wonder what the purpose of such a device would be as it would be relatively small compared to the scale of what was going on upstairs and not large enough to be a threat to the structure itself IE nuisance value compared to the risks involved in actually getting it set up.
A first approximation of the effects of the fuel cloud dispersion on the core column loading was performed by assuming that the fuel cloud spread vertically to fill the full floor height prior to reaching the core. No spreading in the langitudinal or lateral direction was assumed...The comparison shows than an expanded fuel cloud did not produce sufficient loading to fail a core column with the exception of points close to the wing root at the highest impact speeds considered. A more realistic fuel cloud dispersion would have included lateral and longitudinal spreading, as well as removal of some fuel from the cloud as a result of impact with the outer wall and building contents. Under these conditions, it is expected that the fuel cloud alone would not be sufficient to fail core columns.
