Your problems will not be the transformer windings. Your problem will be
massive in controlling corona and high voltage arc over.

Your output circuits will require a pressurized inert gas system to
prevent dielectric collapse of the good old air thereby shorting out
your supply. Your internal circuits will require extensive dielectric
isolation to prevent corona and or leakage breakdown.

Ambient air begins to conduct, become a plasma, at 10,000 volts per
meter [the onset of lightning level E fields]. Dielectric materials used
for insulation suffer E field breakdown at these levels.

If you have the skill and financial resources to deal wirh the
dielectric issues, then a MARX Generator will give you the voltage
levels you seek. The Museum of Science in Boston uses a MARX generator
in their lightning simulator. Contact the Museum for principles of
operation. This will provide pulse power.

If you need 200 watt continuous at 1E6 volts dc, a dielectrically
controlled environment and a flyback transformer technique should get
you there. If you need AC voltage, good luck.
