What you can do is determine at runtime which mode you're in and load the modules based on an if statement in a BEGIN {} block. Such as: 
BEGIN: { 
     if( $ENV{fullbore} ) {
          use Big::Module1;
          use Big::Module2;
          use Big::Module3;
     }
     else { 
          use Small::Module1;
     }
}
