It might theoretically be possible to use the round-trip-time between the two devices, and the finite speed of radio waves, to compute the distance, but in practice at these small scales the travel time is less than the latency in the Bluetooth ...

NFC and Bluetooth are completely unrelated, they can't communicate together. If you want the two devices to communicate, they need to both use Bluetooth, or both use NFC, ...
