Reverse-engineering a BMS

I recently got my hands on a high-voltage battery from a Renault Austral full hybrid. It has a built-in BMS that communicates with CAN and most likely requires the ECU from the original car to function.

Is it feasible to try and reverse-engineer the BMS to work without the ECU, or would I just be better off buying an aftermarket BMS (one from Thunderstruck or something similar) to replace it?
