Aero is driving a lot of EV design choices yes but it’s not as much of a limitation as you are implying - see the Ioniq 5, Cybertruck, F150 lightning or any of Rivian’s vehicles for examples where they’ve traded a bit of range for a boxier, less aero shape (admittedly often with _some_ rounded corners still).

It’s a trade off most manufacturers are not making because the US market is _so_ range conscious but I think it is fairly small margins we’re talking.

I get that... but to a large extent, you should be able to capture a lot of the style of classic designs without necessarily the specific dimensions. I think the modern Scout remake is a decent example of this... another would be the Challenger, which is not original dimensions at all, but absolutely can recognize the inspiration of the more modern incarnation.

With maybe 3-4 base boards, you could do many dozens of different frames and shells. It could be an interesting opportunity for one company to mfg and sell a lot of boards, where smaller coach builders can do the bodies... akin to luxury cars a bit over a century ago.
