Under this scenario, you would actually have more range than a full charge now because the charger wouldn't ramp down and sit idle for an hour or so before being unplugged. It would keep charging at full speed until you unplug it (or precondition the car). And if you needed even more range, just keep the car plugged in longer and start charging up the other half of the battery. Every hour of charge time at the car's full level 2 would give you 10-13 miles of range. So, after 8 hours of charging, you could have 80-104 miles of range, 100-130 miles after 10 hours of charging (not accounting for charger timeouts and other real-world factors, based on continuous 3.3 kW, energy economy between 3 and 4 miles/kWh).
2X capacity batteries may not be that far off. Even 1.5X capacity batteries can be done in 2-4 years and maintain the same size. Look at NiMH progression over the last few years. Before, the largest AA only held ~1900 mAh, now hold 2,800 mAh. Even laptop batteries over the last 3 years have increased capacity by about 40%. My laptop has an 86 Wh battery in it, made 3 years ago. A week ago, I come across a battery in a similar laptop, smaller, but held 97 Wh.
