In Mass I can't pass inspection with the check engine light on. The brake light switch sounds like the best option for unlock but I would suggest a bright RED light as a visual reminder. It shouldn't take long for you to get into the habit of unlocking, when was the last time you forgot to put in the clutch while driving a standard?
I don't have an electronically controlled transaxle. It's all hydraulic, and the only electronics on it are the neutral/park start switch and the reverse indicator switch.

I haven't seen any other wires anywhere on it that would be related to a lockup solenoid, so I have to assume that it's governor controlled, like my shifting.

This link shows how to make a manual torque converter lockup switch for a dodge/cummins 48re transmission. The details will be different, but concept is the same. Beware, there are warnings about possible input shaft damage on stock components. I haven't done it yet, but am thinking about doing it in the future.

This aproach seems to have the potential for significant improvements in city mileage.
