When I first turned up the school to learn to fly (many moons ago), all the instructors were away at the funeral of someone who had been aerobating a non aero Cessna! DON'T DO IT.
It might seem safe, but when it goes wrong, as can happen, is when you find you do need that extra strength in the aircraft after all.
As far as Stall turning to land back on goes, I don't see how you would have the speed to pull up for this on a normal departure. possibly a half spin and recovery,
but he would have to be VERY good or VERY lucky to get away with that!!!
