I've used MO diodes and caps in a voltage multiplier as well, but the
capacitors themselves limited the output current.  The MO caps are in the
range of values to effectively limit hv in series.  I haven't blown a
diode yet.

I once used a microwave capacitors and diodes in a voltage multiplier
configuration. i.e. taking output of microwave transformer to produce +/-
5Kv i.e. 11KV potential.   For this type of supply to be useful you  have to
limit the output current with either an inductor or resistor.  If you don't
limit the output the diodes blow really easily.

Here is a similar system using smaller capacitors.  With this type of power
supply you also have to be careful not to destroy the output inductors.
