Buy an IC thermometer chip and feed the output into an FM input?  Heck, 
develop a whole new module -- a TCDS (temperature-controlled drift 
source).  Have the sensor on a cable so you can put it where the best draft 
is. It could have variable offset and gain, maybe both lin and log 
outputs.  And so on.
