I also wanted to chime in that our solution on the 737 is just to not have brake temperature indications. What you don't know won't delay you.

Carbon brakes work best under hot conditions. The hotter they are the less they wear. They do heat up quickly and also cool down quickly.
Denver and Vegas aside, you are using the brakes wrong on taxi out if you have to wait for them to cool off at the hold short line.
