But, as I mentioned...
I would try to figure out your cost comparison on running the ICE vs using the electricity to heat the car.
Also, I think if it's cold enough and you're warming up the car on electricity only, it may be using more energy than the on-board charger can supply (even with a level 2)... so you may also be reducing your electric only range when you go to drive it.
I actually want to do the reverse... I want the ICE to come on to heat the car up when it's just above 40F. As I'm pretty sure it cost me more to heat the car up using electricity than it does using gas when it's between 40-50 degrees, based on my local gas and electric prices.
