50kV is high enough that corona discharge will be an issue. You will likely want to pot the diode stack or submerge it in oil to prevent excessive loading during the 50kV pulse. The kind of thing you are suggesting doing is common in starting xenon arc lamps. I think they usually have a separate starting electrode or they float one supply on top of the other (for example, putting an HV pulse transformer in series with the high current DC source and then applying an HV pulse to the primary of that transformer).
