Get a copy of Edgerton, "Electronic Flash, Strobe", MIT Press, ISBN 0-262-55014-8 (soft cover)... It's $20 or so, and full of useful practical information on this sort of thing: resonant charging, etc.

Also, get a copy of Steve Hansen's article in "the Bell Jar", where he builds a 250-300 kV impulse transformer, and more importantly, summarizes Fruengel's advice on them.
should get you there..

Ringing is a big possibility in a Marx circuit too, BTW, and greatly shortens the life of your caps.

but sounds like it's easier to design and build than a Marx generator.
