what sort of mosfet or igbt can handle this

IGBTs do get much hotter but they are less expensive at higher voltages past the max voltage of the part you liked which is a very decent part. I should obtain it since its going obsolete and its cost is likely going decrease.

Wouldn't the required SOA be only 7amps for about 20uS?

All I know from your picture is that the maximum current is 7 amps and the blocking voltage is 430 volts.
I'm sure you know more since it's your circuit.
