I was reading an article By Wallace and he speaks of two ways of viewing a grammatical construct.
First he mentions gender shift due to constructio ad sensum or according to natural grammar
Second he mentions normal grammar.
He also suggests that John 16:13 falls into the category of the first idea and goes on to say that gender isn't necessarily an issue.
I read your post and that was how I would have understood it but now I am taking a second look.
Thank you for your response
