Yeah, short trips in the winter are a drag on your mileage... But your method might get you a couple extra MPGs... which comes out to maybe an extra 20-30 miles to a tank. So, you save a couple of bucks each fill up (because you went further than you would have) and over the course of the winter that can add up!

Hmmm... I'm thinking that the gains would be minimal, like "without the block heater I get 33.5 mpg, and with the block heater I get 33.7 mpg!" minimal gains department. Which might just barely offset the cost of the electricity spent on the block heater?
