What features and characteristics would you take from the movie versions of superman and batman to make the best on screen display of Superman and Batman?

For me it would be this:
Superman –
Reeves look, persona for (Clark and Superman), powers, and the suit from Man of Steel.

Batman –
Christian Bale's height and build, Michael Keaton's persona, and the batmobile from Tim Burton’s batman.

I like the suit for both Keaton and Bale versions of Batman but I think I am going with Bale's suit because it allows for more flexibility.
