I would not use wrong as a "being", a condition of state. I would use wrong in an action, she did something wrong, or did not do anything wrong. No one ever "is" wrong enough to be fired.
But as to the basic question: should you say "not wrong enough" or "wrong not enough", the answer is that you probably would use not wrong enough. You could possibly say "she is wrong, not enough to be fired" (putting the "not enough" part as an aside, a clarification, as a comma-introduced phrase).
You could actually say "not enough wrong" although we simply do not generally do that when using "enough". We often use that word order with other adverbs though, like "not sufficiently wrong" or "not so obviously wrong".
