Just use lower value caps in the multiplier and/or add a suitably rated 
resistor in series with each diode.

>> Yes, if you remove the transformer shunts and the filament windings and add more primary windings in the space you would get about 2700v with a full wave bridge. You also need to lift one side of the secondary that is grounded to the frame. Yes very dangerous and yes I'm luck to be able to tell.
