Hey Jeff,
I didn't see your message, it was not in the other thread!
But thanks anyway, I had the same idea as you suggested - I will soon receive some sensors with a blown thermocouple, and there I probably can replace the thermocouple with my own circuit.
As for now, autozero seems to work, and the sensor provides more or less accurate readings, but it is not terribly accurate. I hope to improve that soon, probably by adding the shaping network HP mentioned.
Best
