Oxygen sensor replacement question

Does anyone know if the physical sensors are interchangeable?

My dealership does not stock the piece for the pre-cat cyl 4-6 sensor, which has a very long lead on it (~900 mm). If the actual sensor is interchangeable though, I can merely splice the wires onto one of the other sensors with a shorter lead.

As an additional point, possibly of interest, the retail price quoted for the 750mm lead-equipped sensor was ~$250, while the post-cat sensors with a shorter lead retail for ~$149. It sounds like one expensive run of wires!

Thanks in advance.
