So in your situation, the pumps must reload to apply pressure and fill the ballasts with water removing the air which applies forward force and impedes any diving. You need to be that patient, in reallity it lasts more than 2 minutes I imagine which means skippers do emergency blows really at last ressort because any time on the surface is deadly.

This might work but will make so much noise that you might as well just blast stereo music because it will probably be just as loud.
