This morning we measured the Hall C IA output on the oscilloscope, and exercised the Hall A & B outputs to verify if there was any crosstalk during operation.

Tl;dr: We did verify that when operating the IA outputs in an aggressive manner (pushing towards the limits of the outputs) the existing IA driver does have crosstalk across channels.
