Ahh Brian...Interesting, but how do you see this as being meaningfully different from a body kit on an AWD Tesla?
Almost all builds fall into 2 categories.
Rebuilding/restoring something old or broken to return it to its former glory
Trying to improve looks, performance, or functionality
My build would fall into the later category. In many ways this is what the majority of kit cars are; taking the drivetrain/power unit from a donor vehicle and create some more pleasing/aggressive styling (granted very subjective). Sometimes they try to improve the performance with different suspension, or with reduced weight.
To answer your question...It might be very similar if I do something like Vaydor (Infiniti G35) or Valarra (Corvette). I do not love the Tesla interior (or exterior for that matter) so I am likely not doing a body kit on a Tesla.
