Anyway, answer to the question is no IMO.
If it's Debuchy and a replacement for Ba then yes. Cisse will improve playing centrally IMO and the advantage of Debuchy over Simpson is massive.
That should more than offset the downgrade we'll almost certainly have as Ba's replacement likely won't be as good as he's been.
But a straight trade and no other incomings leaves us very short up top IMO.
