The Detail & Scale has two shots of the leading edge flaps down with the wings folded, one is a TA-7C and the other is an A-7E. In both cases, the inner wing flaps are down, but, the outer wing flaps are up on the folded outer wings.
Almost all of the other shots I have seen of the A-7 with the wings folded show both the inner and outer leading edge flaps in the up position.
So, it seems that you could do it however you wanted. (one really neat shot shows all four leading edge flaps down, as the wings hit about "half folded" while the crew is looking things over)
