You can fly a simulator of another model, but it is a different aircraft and feels different than your model.
To make it fly exactly like your model, your model would have to be accurately measured in maybe 50 different ways and code would have to understand the 50 different parameters. Each motor thrust, total weight, rotational moments (how much inertial to spin it on each axis), throttle setting to thrust curve, motor lag function curve, altitude you fly it at, temperature, humidity, linear and rotational drag (air friction) curves, battery voltage sag curve, power wiring losses..........
Man years of work.
