Or at least one of these in Tesla:

EDIT:
To further this thought, what I would truly wish would happen would be that A Tesla-like "drivetrain platform" were available to boutique shops who could build whatever type of cab they wanted onto a standardized system.
I worked with a guy in the 90s that took a Corvette Z base and put a 1938 ford on top of it.
I'd like to have the same be done with Tesla drive train bases - where you can have an upper made to fit the lower. Clearly, there would have to be safety standards to be met, so don't waste time arguing that point...
