If you had some kind of drop out battery tray then it’s entirely possible. Of course such a thing would be entirely custom but not too difficult to conceive. Maybe a thick batt box like Mike sells, with an interlocking attachment of some form, that can be quickly un-snapped to allow the tray to pull out the side, or with a little more ingenuity, out the bottom. The actual batt would be secured to the tray and you’d actually be swapping trays in the pit-stop. No need to un-pin and remove the body, simply lift the side. Sounds reasonable?
