Seems a better place unless there is something in the way like a fuel cell, oil tank, spare or such would be as far forward, to the right, and low as possible.

I would look to the rear of the car first for weight reduction. Exhaust, euro bumper struts, rubber bumperets delete or euro's, rear seat backs, RS carpet kit, rear under carpet pads delete, fiber lid and or tail...
You can look into something called "polar weight", it's almost as important as "unsprung weight".... getting the weight inside the pole, i.e. within the perimeter of the 4 tires is a lot more important that bring the CG up a fraction. Moving the battery within the wheels is and a little bit higher is a better compromise.
