Let's make this clear: It is true that when costumes are translated to film changes must be made. But that's the result of translation, instead of replacement.
Batman is officially gray and black, which is sometimes represented as gray and blue.
What changes between comic and film is colour theory. Batman's high-contrast gray and black costume works better on paper than subtle changes in tone.
This proposed 'accurate' costume is gray and black, but the contrast isn't as high. If we wanted, we could have the black part of the costume reflect blue under strong lighting, like the costume in Batman Forever.
So you're right, changes must be made, but that doesn't mean we should suffer sub-par replacements.
