Pretty sure it wouldn't matter, I'm pretty sure you can do similar, without the actual details. I mean if azure is platinum blonde or strawberry blonde no one would notice, no one really knows how long her hair is either. And we know amber has some sort of short reddish brownish hair. Same thing with faces I mean you can morph the models a bit right? Amber being a bit broader faced and puffier cute with freckles and Azure being stancher with paler skin. No? Those damn sunglasses hiding much of her face most of the time anyway.
And as for clothes, you had them wearing more and more normal clothes anyway. I'm not saying that you should pursue city of supers over any other project, I'm just saying as I know I have a ton of old projects myself, that there will come a day when you get a good idea for that group and that they were made with old ink shouldn't stop you from making it.
