Why not skip the bleeder entirely, and make a current discharge circuitry when the session is over. If the anode voltage is very high then stack some thyristors and fire them with opto couplers. So when you hit the big switch it turns off all power to the power supply, except for the auxillary circuit that keeps the draining alive and then shut off . Not very compicated to do and you get rid of the bleeder heat.
