Good to see someone coming up with something new like this
You could probably improve the thermal time constants quite a bit using tiny SMT diodes and cal heater. Also very thin lead wires to the sensor. Finally consider enclosing the sensor from drafts which would greatly affect accuracy.
The sensor and ref diode bias current decreases as the battery is depleted, but this probably isn't too much of an issue.
