I understand your aim is to get your scan beefed up for manual approaches?
Why not Microsoft Flight Simulator? Gives you all sorts of turbulence/wind/visibility. I think you can disable some of the instruments or make them go dodgy. You also stand the best chance of getting a panel that matches your chosen plane - which is the key thing. It may not be picture perfect - it might be - but it should have the instruments in the right places.
Having said that, I'm not sure why Airline Sinmulator won't do what you want.
