You'll end up with a more reliable configuration by using multiple,
identically constructed, capacitors in series since the voltage stress
will be equally shared across each cap. Each 30 mil dielectric cap
should also use 2 or more dielectric layers to reduce the probability
that a defect in one layer will cause dielectric breakdown of the unit.
This is one construction secret that commercial HV capacitor vendors use
that you can as well...
