I do agree, it will not be as good as a locking differential. The vehicle we be utilizing this system in a <5 mph range, so I proposed the traction control would have time to interact with the loss of traction. Also, I have further ideas, like the ability to brake one tire at a time to help position or spin the vehicle on a trail.
Instead of controlling the ABS, I saw these hydraulic eBrakes, or turning brakes that could be actuated for controlling the brakes while not interfering with any existing system.
Thanks for the input.
