Is Neurokit2 suitable to build a 3 channel gold standard ECG device from it?

I suggested to combine OpenBCI with Neurokit 2:

The future of OpenBCI: a Fusion of OpenBCI with NeuroKit2 & real-time Databases wich are based on InfluxDB?

• On the Neurokit 2 Github, we can see that Neurokit has in this example 5 physiologal channels.

• But for for instance to build a gold standard ECG device, 3 ECG channels are required. And Neurokit2 has only one ECG channel.

For the Gold Standard in ECG which means the highest accuracy 3 ECG channels are required. I have shorlty reviewed this in my review about the accuracy of PPG smartwatches:

090. Review of Accuracy Studies of Consumer Grade Heart Rate Monitors: Methods, Testing Protocols, Reference Devices

• It remains to be seen, it we could replace other channels with more ECG channels. For instance PPG signals which are not very accurate. And EMG which are not really of interest for the applications I describe here.
