So, there are a few companies like JET that sell resistors to replace the IAT so the engine thinks its cold and richens the air fuel mixture (with the intent to make more power).

So, heres my question, would it be possible to add a resistor inline with the IAT sensor to increase the resistance slightly leaning out the air fuel ratio (with the hope to make gas mileage better)?

Example: Suppose the IAT reads between 5k ohms (cold) and 8k ohms (hot). If you added a 1k resistor in series with the resistor, (I would use a wideband to see how it affected it) you might be able to lean it out right? Or run one in parallel to decrease if the resistance was inverse to temp.

Or would the O2 sensor reading just adjust for this?
