Is it possible to replicate a bungee launch in SITL?

We are having a stall after a bungee launch when the plane reaches to the given altitude. The problem is that the plane speed goes down the minimum required speed. I wonder if it is possible to replicate it in SITL and measure the speed of the plane during and after take off by playing with Ardupilot Parameters.

realflight has a bungee launch option
