Re: "...a man who is older and wiser than Clark Kent": Does this not worry anyone els
I can see the "seasoned Batman" thing working pretty well after thinking about the story potentials. Who wants to see "young Batman" after we've already had Batman Begins and The Dark Knight? Also with an older Batman we won't have to reintroduce many of the key elements and maybe have more of that Batman the Animated Series/Arkham Series feel to the series. Not to mention the fact that a "seasoned Batman" will have more issues with an alien masquerading as a hero since he'd only ever truly trust allies like Alfred, Nightwing, and Robin (along with a few other soldiers of the Bat) after his trust had been shattered time and again with people like Harvey Dent, Catwoman, etc. With Bruce being older we can see how the crime and filth of Gotham has spread a dark cloud over the once shining sun of hope Bruce intended to bring to the city when he first put on the cape and cowl of justice. Superman's characterization doesn't have to put him beneath Batman, but rather Batman would try to impose a mistrust into Superman through his "wisdom" that Superman just can't allow in his soul because he is that beacon of hope Bruce once intended to be.
