Nah. Getting the right kind of explosive package and expertise for this would require direct DOD involvement, the industrial explosives with which the oil industry is familiar and comfortable are much bulkier and not suited to this kind of application, nor would the Coasties be comfortable touching them since the closest they come to explosive handling is packaged gun rounds, their expertise with demolition explosives and air-delivered ordnance is extremely minimal.
The 'top kill' technique that's going to be tried is a non-explosive oil industry method of the sort BP is most comfortable with, everyone else on the Federal 'Task force' (cough) side is just kibbitzing and trying to avoid being in a position to catch any blame if it fails.
