These are pretty uninspired, and many of them aren’t any more suited for battle, even on a comic book level of realism. There really are possibilities that would be more fun and stylized than these, but more functional than the original. That said, yes—if a character goes into battle with their midriff exposed, you should be well aware that you are portraying that character as a total moron who really ought to be dead by now. Obviously, there are exceptions. Wonder Woman has superhuman resilience that makes body armor less of an issue, and comes from an all-female culture where modesty wouldn’t be so much on the radar—so showing her thighs and shoulders is all well and good. (I take more issue with her cleavage going everywhere, since that’s actually impractical even for her.) But Huntress? Can you picture her in the midst of her costume design, deciding, after many long hours of consideration, that the murderous thugs she fights just NEED to witness her navel, safety be damned? NO, NO, NO.
