lighter better

A Model 3 also ususally hauls only one person and not much more, and has a limit of 5 (or is it 4?) passengers and some 900lbs total weight of cargo and passengers (although I'm sure you could add more than that). But if you could lighten it and replace that mass with even more passengers and/or cargo, then miles per kWh per passenger or lb of cargo would also increase considerably.

This whole thing reminds me of the BSFC efficiency of an ICE being at around 80% load. But if you drive around constantly at 80% load you'd actually get worse fuel mileage.
I recommend that you examine testing cycles and the other physics necessary to flesh out the details associated with the thesis.
You're describing dynamics that are not prescribed within the constraints of the mandatory test protocols.
The things you mention can all be numercalized.
All the mathematics will be required to have an actual look at what's discussed.
Without the mathematics we cannot proceed.
