That is a theoretical view. First the aircraft need an acceptable approach speed, a reasonable runway performance, and climb performance. If not happy wings has to extended. (Same story for the Concorde.) The Aerion seems made just for fulfill that conditions. I guess it will be a low runway-performer, not good for a business aircraft, build for stability and safety.
Usually are constructed after the engines. Aerion is opposite. They changed the engine already. A successful supersonic aircraft need to solve the engine problem first. Let me give some figures at FL650 M0.92 is about 155KIAS. AtFL800 M3.0 is about KIAS250. A nicely constructed aircraft(like wingsonly acft) can maintain a L/D of 40.
