	No way.  The primary of an NST will "saturate" at about 1.2 X the rated
working voltage, and increasing the voltage beyond that limit will just
result in heating and if you raise the voltage high enough and leave it
on long enough all the smoke will come out of the transformer.  So, any
scheme of cascading transformers like this is bound to failure from the
very beginning, as is trying to run 120V NST's on 240V, etc.  In the
case of trying to drive the primary of one transformer from the
secondary of another the current limiting inherent in the leakage
inductance of the transformer will prevent any damage, but you won't get
anything at all (or at least very little) out of the secondary of the
second.  Of course, you can probably also find a way to puncture the
insulation between the primary and secondaries, or between the primary
and the core.  DON'T TRY IT!!!

P.S. Terry - do you have anything in your archives about transformer
saturation?  A  lot of people need to read and reread it.
