How do the limit in the FSX Mission move to further ?

Let me explain.I want that the aircraft change to a person who can walking, climbing, shoot, enter the buildings, find items, drive a car, see video in the logbook, make the air volumetric, raining on the roof, wet buildings, make the fire blazing, grass move as the pixel shader.Is it possible to script those with GPU programming language ? Else make my own DLL file with GPU programming ?
