If you did the Top Hat now, and flushed the system with drilling mud, you might make it work. The previous top hat was just going to be on only one of the sections of broken pipe.
The top hat problem was a combination of natural gas, pressure and sea water. You would need a way to "seal" the bottom to prevent sea water from contaminating the natural gas.
