The easiest way to implement would probably be through a sister-series/support race (while everyone is already there). It'd be too difficult to outright break the decades of momentum the 358 ci V8s have had.

It’s less a consideration of difference between passenger cars and race cars and more a consideration of how much difference there is from one passenger car to the next passenger car compared to how much difference between one race car to the next race car.

Chevrolet will be different from Tesla will be different from Mercedes will be different from Honda. Those differences will be in how the pack is installed in the vehicle, what the battery chemistries are, how the battery cooling systems are integrated, etc. Even whether the battery pack is assembled as modules, pouches, or cells. None of those companies will accept settling on a standard that they themselves don’t have a heavy hand in defining and they all have different approaches today.

NASCAR can mandate that battery packs will be installed in a specific location using specific standards. Just as they currently control chassis specifications, engine displacement and boosting specifications, fuel tank size and location, etc. That sets up well for making battery swapping a pit crew operation, just like wheel swaps are a pit crew operation.
