Why do you need such a high voltage, isn't the megawatt a low voltage supply?
For more current, have you considered paralleling transistors? It appears a small value "ballast" resistor is required on each emitter of the transistors in the parallel, to stop one from trying to eat all the current on its own.

scroll to the section "Thermal mismatch (problem with paralleling transistors)"
Alternately, your new high current transistors might benefit from a lower current bjt acting to boost the gain, a Darlington "pair" made from discrete transistors.
