The no commercial sonic booms legislation might go away if it were an American company asking for it. I have no doubt that the Concorde being foreign owned helped speed that legislation through Congress.

Of course being a little no-name company won't help matters much here, but I expect that actual production of this would involve a partnership (or probably buyout) with one of the big name companies that have a lot of congressmen on their payroll.

There has also been a lot of research into minimizing Sonic Booms since the 70s. Military jets typically don't care, but passenger jets could definitely benefit.
