Can someone who knows a lot about production and in-studio craft answer a question?

Is it possible for Bon Jovi to produce the heavier record most of us want considering Jon's voice, or is what we are getting the limit to what can be achieved?

Let's ignore he has no desire to write that kind of music and would never be able to do it live.

There's no excuse for the shitty songs but are we getting the best studio Bon Jovi possible?
