To answer the initial question of this topic: No, you wouldn't.
That is, 99% of the people who think they can, will mess it up. I'm a (former) 737 pilot (still type-rated) and instructor. I have had many flight sim enthousiasts in the Level D simulator and I'll tell you that 99% of them would have totally messed it up without my help.
Even if you can properly land it in the Level D sim, landing it in real life is a totally different thing. I remember the first time I had to land a 737. I was able to land it perfectly in the simulator, but in real life you're scared sh*tless. And I even had a captain and an instructor with me.
If you ever get in this situation, contact ATC and do an auto-land.
