The problem is, it depends on what you mean by "shell". I agree that most Tesla vehicles are fairly spartan from an interior standpoint, but I don't see that to be a drawback. I guess I'm not the target market for a "luxury" car, even though I've got a 3, and I'm also on my 2nd BMW. I simply don't care about butt massagers and cooled seats and chilled glove boxes or whatever we're supposed to mean by "luxury". I want a quiet, comfortable car. It doesn't need the 7000 buttons that come in a new S-Class today. But I don't want BMW to take a Model S drivetrain, and put their horrible nav system on it, their keyfobs, their UI. Part of what's so great about the Tesla is that I just walk up to it and get in, and it works. They've rethought enough of the car experience that it's hard for me to draw the line at what I'd want BMW to do. I guess I'd want BMW... seats? and maybe interior finishes/colors? Maybe? A bit more thought into finishing the trunk? But certainly not just a BMW with a tesla battery and motor.
