I was listening to the song "Notorious B.I.G" while playing Fallout 4 just now, and the most random thought came to my mind; replace the stranger with Biggy Smalls, and a custom audio clip.
The Mysterious Stranger appeared in VATS right at that part in the beginning where they're like "No-no-notorious!" and I thought it was pretty hilarious, so I came here.
This is a stupidly ridiculous idea, and I'm hoping someone can make it happen.
