Yes, yes, yes! It appears that Max will have that sort of covert, late introduction in the film a la Man of Steel. I like the tone (color & theme) very much.
I recently saw Mel's II and III again and was transported by my nostalgia of the first time I watched them. How do I say? I just love me some bad a$$ stunt driving and some early Mel Gibson to boot.
But I look forward to Tom Hardy's spin ... now that you mention it though, I enjoyed The Bourne Legacy very much only because of Jeremy Renner (I haven't seen any other Bournes, and of course I've seen The Hurt Locker) and think that would have been interesting casting for Max as well. Hmmm.
