Just been reading this through with interest. I didn't get all the way through so please forgive me if someone else has suggested this already. One of the guys in the office had a look over my shoulder (a former marine engineer and current biker) and he suggested protecting the thermostat casing from the airflow. That way it will only react to the temperature of the water and not the cooling effect of passing air on the casing which might transfer to the thermostat capsule.
Interesting thought, that.
But ... the cool (freezing?) air passing over the 'stat housing will - if anything - tend to keep it closed for longer, which is exactly what is needed to boost engine temperature.
Unfortunately, insulating the housing will have the opposite unwanted effect.
