Technically, I am sure it is possible with todays manufacturing, material and 3D printing capabilities etc., but I am thinking the biggest battles Boom faces will be regulatory.

Getting the aircraft certified by every country's aviation body is going to be massive (unless they restrict flights to within the US only, which will basically negate the positives of international supersonic flight).

Then there are the battles against various environmental lobbying groups, like Concorde had to do, who will try to enforce curfews and restrictions on supersonic flights over populated areas.
