While I really like the idea, I think we're still too far out tech wise to make it a reality in a way that it would live up to the dream. EVs of today are really heavy and even with a fairly small range, I fear the weight from the batteries would butcher any kind of driving experience for a car like that. In time though, I hope we get plenty of old cars retrofitted to be EVs as the tech becomes lighter, cheaper and more standardized.
The point isn't that it can't be done, EV conversions have been done for decades at this point, but that you'll get a car that's a whale compared to the original.
