Therefore " Both of them will be running much hotter then is allowed. and both will overheat, and consequently blow.

My way would be , to drill another mounting hole on the same heat sink, mount second TR on new place, and just run fly leads to first transistor.
Another thing is to separate bias to the transistors, by inserting two 10 ohm resistor into basess.
Or by separating their outputs by heawy duty resistor 0.1 or 0.33 ohm, inserted into line of Emitters.

Thank you ,,,George
