no that wouldn't be realistic. Batman is to keen and cunning for that. Remember he has beaten superman numerous times not only in fiction, but the in cartoons as well.
in batman superman worlds fienst, batman casually threw superman across the room like nothing
But those are interpretations by people, if you look at it scientifically, it wouldn't happen. They shouldn't go by the interpretations of what has happened in a comic or whatever or a cartoon. They should go by what would realistically happened if a good fighter went up against a man who moves faster than a speeding bullet and is basically everything-on-Earth-proof. What would happen? That is how it should be viewed, it should not be viewed as whatever a writer decided would happen, but rather what actually would happen if such an alien existed.
If a person is faster than a bullet, well basically if you were about to shoot him with a gun, he is faster than said bullet, he could theoretically rip Batman's finger off before the gun would even be out of the holster. How can someone who is faster than a bullet have reflexes that are so slow that a quick fighter could take advantage of to throw him anywhere? That is writers wishful thinking but scientifically not possible.

If they took things like that into account, then you are talking about a realistic encounter.
batman has also never used his full arsenal or power against superman either. so it's a stalemate
Unless he has a bomb or something that could cover the entire planet with Kryptonite and extend into space and that it is fast enough to catch Superman and strong enough to make Superman weak enough to where he is actually almost human, then I seriously doubt that his entire arsenal would be of any use to him.
If Bane breaks his back in the comics and movies and everything what chance would he stand against a super fast super powerful alien that could just pick him up and handcuff Batman's hands and feet to the top of a flagpole on the other side of the globe before Batman has even blinked?
and Superman would never use his full power against a human which Batman is a human against a super powered being .
He could use his full speed though, that wouldn't even be close. I think the only reason Batman would ever win would be favoritism, not a well thought out scientifically accurate or plausible scenario.
