A few things to think of though:
1) Realistically, single level loading is the obvious choice.
2) I suspect that being what ammounts to a 'freight' car, they don't need to meet FRA.
3) The carbody of a well-optimized design isn't bad - the Pioneer IIIs in unpowered form where 52,000 lbs
4) But a car carrier has no air conditioning, seats, PA system, toilets, etc. Tha'ts a LOT of weight. Ditiching windows helps too.
Could a viewliner-sized autorack be built? Likely. It's the form factor I'd study. And if you keep the weight with cars in the sub 100,000 lb area, then going 100+ isn't a big issue, though on the NEC, you'd likely need two motors to do the trick. Diesel? Forget it.
