I was going to suggest maybe updating the first post with the current roster plans, as it might help out as well. Yeah I can imagine how tough it can be for the SNK sprites just due to how the shading is set up.
Here's some other character samples, not sure if you've had all of these suggested or seen the sprites yourself, but I figure it might be good for ideas. Alice for SNK might be fun, Hinata/Akira from Rival Schools might be great too, or those new sprites for the more accurate Decapre by tJun, loads of potential. I bet Adelheid will be great, the preview video was awesome
