Placing the battery under the cargo mat in the foam tray with a nice wire to the front may be an option. Raising the mat by about an inch if required would be no problem. Ventilation for gases may be a problem if required. I'll investigate this problem.
Our Miata has the battery located in the trunk, it comes with a tube that exits beneath the car. If I remember correctly, all my old motorcycles had tubes attached to their batteries too.
