Missed that one...
It is not possible. Brakes are proportional and brake lights are on/off. Having your trailer brakes being either "on" or "off" would not be very helpful IMHO. I laugh even thinking about it.
A brake controller is a complex inertial system that varies braking strength based on your settings and preferences and the forces being imparted on the vehicle either by accelleration or decelleration. You cannot replicate that by connecting brakes to your brake lights.
My boat trailer did have one of those tounge mounted hydraulic assembly things...worked OK, but didn't really "grab" the brakes in an emergency stop...just helped a little by keeping the trailer behind you.
