Switching between measurement Path and Calibration Path

Hi, I have this idea of using switches to toggle between measurement path and calibration path.  This way, I can write a automation software to make measurement via measurement path.  After some time, it will then switch to calibration path for auto cal with ECAL.  The path length will be the same in this case.  Can I assume that reciprocity or symmetry of the error network is valid in this case?
