That wouldn't have been a good idea IMO. If you think about it, this version of Green Arrow is completely different from Batman in terms of training and motivation. The whole idea behind this show is that Oliver has spent 5 years in hell and has now returned FROM hell to fulfill his father's wishes while the idea behind Batman is that he returned TO hell (Gotham City) after years of training to turn his city into heaven. Plus, there is the whole family and bodyguard thing that wouldn't have been present in a Batman show.
On top of that, Batman is too "big" for television (minus animation) and the current special effects can't do him full justice. That's the main reason why Green Arrow is a better choice in general.
Love this show so far. Every episode so far was better than the last one. It wouldn't say the show is great yet since it's too early to tell that but so far it's good enough to grab my attention and keep me hooked. It is also far more faithful to the source material than Smallville ever was. Though it's still not exactly the best adaptation you can do of Green Arrow, these first 3 episodes have stayed more true to the comics than the entire Smallville series did in 10 years and looks like it will continue to become more and more like the comics. Also, whether you agree that shows like Smallville and Arrow should be faithful to the comics or not, a show like Arrow deviating from the source makes so much more sense than a show like Smallville deviating from the source because the whole point behind Smallville was that it was Clark's growth into the Superman we all know, except that by the time he becomes the Superman we all know, everything is completely different from the comics - most of the villains were introduced were altered, Clark/Superman's relationships with his supporting cast and villains were completely different than in the comics, Clark already encountered a lot of other superheroes and even became part of the Justice League before he became Superman, characters like Jimmy Olsen are dead and Lois already knows Clark is Superman (when he BEGINS his career as Superman). If you're going to make a Superman show about Superman becoming the Superman we all know of, why not make it like the comics? Why not have everything become like the comics by the end and make it feel as if any classic Superman story from the comics could've taken place after Smallville's ending? SO much wasted potential with Smallville.
Arrow, on the other hand, is not trying to sell itself on "Oliver becoming the Green Arrow you all know of". It is trying to be a show about a vigilante dressed in green that carries a bow and arrow and tries to clean up his city. It can be viewed as an Elseworld story. It can be a story about Green Arrow becoming the Green Arrow we all know and love (and it arguably is trying to be that but that's too early to tell), but it doesn't have to necessarily be that because it was never selling itself as the show where "you will see this guy become the character you all know!" like Smallville was. Arrow, for the most part, was trying to be and was selling itself on being a show with the realistic and gritty setting of Nolan's Batman but about a badass archer vigilante.
That scene was oddly edited though.
