(I'm just gonna copy/paste my message from chat):
Regarding the Concorde and TU-144, since they both only carried first class/business passengers, would it be possible to bump their capacity to make up for the seat-space calculation, because right now you can only get 51 business pax on a concorde, while the real one has about 100 seats with 38-inch pitches. I think as the formula currently stands that'd call for a 75-80% increase in base capacity, but that might throw things out of balance, so maybe a 40-50% pax capacity increase would be sufficient.
