Certainly not for the beginner and certainly not for the experienced when operating beyond known and tested figures. If I added a passenger I'd have to add close to 100ft. If you are going to do it, it would need to be a sizeable margin to be sure you could do it every time, be at the top of your flying game, be well practiced and be alsolutety ready to action on a shutdown.
Do you have an airspeed and height gate or just a height?
What rule of thumb for temperature and density altitude do you use?
What analysis of the 'power loss' do you allow for before deciding to shut down the engine?
