I think out of all the characters, the easiest to redesign without changing the presentation much should be Black Canary. In the animations, it becomes evident that character designers would swap fishnets for opaque tights that it’s not a big loss anyways. What if she has several pairs of tights to wear in her closet that aren’t always fishnets that it makes sense this way?
It seems some people figured this out with Wonder Woman that if she can’t wear shorts, it would be a short skirt instead. (Strange as it sounds, they came to that conclusion.) It’s always possible to do alter the appearance much without significant changes. In the case with animation, it’s done for simplicity but it’s always doable.
Though that would be realising it’s not that big of a change.
