We've done option two multiple times in the past couple centuries, so I don't buy it. Hell, massive changes happened in the past three years. For example, why can't we move to a 7 hour work day and get off work an hour sooner (or start an hour later)? That'd solve most of the problems DST attempts to solve.
Option 2: Fundamentally change the structure of employment throughout the entire economy.
One of these is easier.
