I think this is a good idea but a better one might be to look at alternate pack designs. It sounds as if the stock battery management system may have a systemic problem and analysis might lead to a pack with longer legs.

I actually see no real reason to refurbish my pack and bring IMA back online, aside from sheer curiosity about the project itself and then getting to play with the hybrid functionality.

I am not a Honda IMA expert but I remember seeing a Honda chart showing how the electric motor provides low-end torque. What I don't know is the extent the Honda control laws stress the batteries. Monitoring the temperature would be a good start.
You've got a vehicle with outstanding, low aerodynamic and rolling resistance. Bringing the ICE back to OEM spec seems like a natural especially if it can be done in a way that extends the battery life.
