As a pilot - you would be making a poor choice. You are over water you will need to ditch in the water why on earth would you climb?
Poor choice: Don't think so! I am a retired career Air Force and retired major airline pilot, and I will assume you did not actually read the post with understanding. A twin engine airplane has two engines, so if one malfunctions, you are not going to be ditching unless the second one quits also. Even if I was in a single engine aircraft, I would gladly exchange excess airspeed for increased altitude to get maximum altitude at best glide speed, no matter the DCS risk to the diver passenger. Airplanes, even big ones, are able to glide some distance even if all engines are lost and you are able to keep the aircraft under control (ask Capt. Sully Sullenberger of Miracle on the Hudson fame). In such an unfortunate and dire situation, altitude and time are your friends--proximity to the ground and reduced time to impact/ditch are your enemies. Altitude and time provide you the opportunity to run emergency checklists and hopefully correct the problem, as well make emergency communications letting as many people know who and where you are, and the nature of your emergency. If you have to ditch in the sea, you want as much time to get that set up because it is not easy under the best of circumstances, and can be disastrous with even minor mistakes.
Divers can, and do, unnecessarily put themselves at risk by flying too soon after diving because they do not think about or understand all the problems that can occur in flight, nor do they know or understand what pilots are trained to do in emergencies. To me, these divers are in the same category as "trust me" dives in an overhead environment without proper training or equipment. They don't know what they don't know!
