Well, one interpretation of the problem is that anything based upon "what is prior" and "what is posterior" with a first step is interpretable relative to the ordinal sequence of natural numbers.
Rules of inference are stepwise syntactic transformations.
How do you formulate a deductive theory which is not interpretable in relation to the ordinal sequence of natural numbers from which you wish to assert independence?
Aristotle has a discussion concerning four forms of priority (which, unaccountably, turns into five forms by the end of the passage). Deductions and ordinal sequences are bound in this way and cannot be undone.
Your second paragraph appears to ask for a distinction which is indemonstrable and inconceivable.
Incompleteness merely reflects that numbers and deductions cannot be placed into the relation of priority with respect to one another.
