Max was quite overused about ten years ago. It might be a little less so by now, but I'd put the fact that you (and your son) will hear it a lot onto the list of things to think about. On the other hand, Walter White is not a good guy. lol (Seriously, I would not be worried about that last one, since Breaking Bad is ending this year.)
max walter that way he can have granpas name in there but a more now name for first name plus max will be easier to spell in school my poor son is christian very long
