Konami could put the camera angle low over the shoulder of the keeper maybe having the goal slightly transparent should you step back to the goal line and you'd have to time the dives and direction to make a save, X could punch/kick and A could catch.
the main problem would be standing around for 90 mins should you sign for the top sides, only having to deal with the odd shot or two.
i'd go for it as keeper is actually my preffered position anyway.
