Totally against reasoning.

The metal conducts heat pretty well. The base of TPMS are metal connecting to brass valve stems mounted to metal wheels. Yes it can be cooled but again I don't know what temperature accuracy you are expecting for the tire reading?
Air inside a tire is a poor conductor of heat and rubber is a good insulator. The hot spot of a tire is buried deep inside the rubber structure at the edge of the steel belts. Only way to get a reasonably accurate tire temperature requires a needle probe. We did this all the time in Indy racing where tire temp accuracy was recorded to the nearest 5F.
OE internal TPMS have the pressure sensor buried in an insulating plastic holder. Not aware of any that measure or report temperature but there may be one.
