I'm currious to see what will happen.

Things like this were used directly for the generation of high voltage.
See the "rheostatic machine", developed by Plant� (the same inventor
of the lead-acid battery):
http://www.coe.ufrj.br/~acmq/lef595.jpg
It consists of an array of capacitors and a commutator mounted on
a cylinder that connects all the capacitors alternately in parallel,
being charged by a high-voltage battery, and in series.
A kind of Marx generator where the capacitors are first charged in
parallel and then assembled in series.
His book describing the machine is available at http://gallica.bnf.fr.
In your system, you charge the capacitors one by one. Another
possibility, that I have seen somewhere too.
