The impact is not likely to translate itself into a $5 million AAV increase, because, as you said yourself, Martinez is horrible defensively, older, and really not geared towards being a full-time catcher. I don't need to be a businessman to know this, but i know that teams place a certain value on every aspect of a player's skillset, and that translates into money. In V-Mart's case, chances are it's not going to translate into anything more than 13 mill per year. The problem, IMO, isn't AAV, but rather the amount of years, that's the part where one team may end up shooting themselves in the foot. Anything more than 4 years will become an albatross at the back-end of the contract.
