How do I combine multiple Common-Mode signals to the feedback stage of a multi-channel biopotential amplifier which feeds back to the ref electrode?

I wish to design an 8 channel biopotential amplifier to measure EMG signals. In the figure, the signals from electrodes (E1 to E8) are fed to InAmps (IN1, IN2... IN8) and Band Pass Filters (not...
