Lloyd, I rather imagine that many women will applaud your ingenuity; but this reading is, to put it mildly, problematic.

The Hebrew of Gen.3:1 reads something like: ‘the serpent was shrewd out of / more than every living thing of the open-field’. The LXX reads: ‘the serpent was most intelligent of all wild beasts on the earth’. The obvious sense of both these constructions is that the serpent is included in the group of creatures that live in open country (cf. 3:14). A more complex construction would be needed, I think, if the point was that the ‘serpent’ was not part of the group.

All sorts of other objections arise: Eve clearly distinguished between Adam and the serpent; the serpent is cursed and made to go on its stomach and eat dust (unlike Adam who will have to eat the plants of the field); the serpent’s offspring with be in conflict with the woman’s offspring. There is no basis for your claim that ‘According to Genesis and Paul there were only two creatures in the garden capable of talking’. Adam is dead (Paul is quite clear about that!) and cannot be the serpent which is the adversary of the early church. Adam was ‘not deceived’ simply because the serpent spoke to Eve, not to him - Paul constructs it in this way because he is developing a correspondence with the activity of false teachers who prey on gullible women.
