Unfortunetley Nolan's Batman doesnt fit with GL or any other heroes
People keep saying that....
Nolan himself has said that Batman working with other superheroes has been done succesfully in other media, and that it can be done in film, but the thing about HIS Batman is that he didn´t get the idea of costumed vigilantism from anyone else, this meaning, that Bats is the first superhero in this universe (same as in the DCAU), so chronologically speaking, would mean that all this other guys show up after him (including superman, and that can be fixed); that way, it could work perfectly fine.
Also, Nolan´s Batman might not be the Bat-god (yet), but if we talk about "in the field", he seems far superior to comic book Bats to me, I mean, his "anthics" and skills makes him look as if he had powers (to the regular folk in that universe), for example, he "flies", he "dissapears", he can take on an entire swat team without breaking a sweat, so I think is perfectly possibly to see him fitting with other heroes, specially now that they´re handleing (sp?) them in a more "verosimile" way.
Just my two cents.
