Hmmm... for designs in which the tank is not integral with the aeroshell, how about just having a port for blowing warm air into the shell from a ground-based heater? Hook up the Coleman hair dryer to keep things warm; disconnect the umbilical when it's time to launch, and the only extra weight is the air-hose fitting (and any ducting and baffles that may prove necessary). For one of these conical-aeroshell-over-everything beasties, just have forced-air heating built into the launch pad, blowing hot air up its skirt.
