Assessing center of gravity

The metal mentioned replaced the metal cabin air box, so likely no change.

But weight and placement of an oil tank is insignificant. The big objective is moving the 500 pound lump aft 3+ inches.
In concert with the pursuit of changing the large weight mass aft, perhaps assessing lowering the center of gravity....is it possible to locate the oil tank lower in the chassis? Possible to lower the battery lower in the chassis? Perhaps lowering the seat height a touch?

All of these may be on your radar already.
