I'm pretty sure Clinton would win in this scenario. What killed her was her narrow losses in a bunch of big states (Florida, Pennsylvania, Michigan, North Carolina), not the fact that North Dakotans count more than Californians.
However, this proposal isn't happening. There's no constitutional way to do this on a federal level without an amendment, and no legislature would agree to do this on a state level because it would be unilateral disarmament.
Remember that this would mean Republicans would get electoral votes in MA and CA too. It's not like Clinton won 90% of the statewide vote in either of them.
