I think with chris it's different. They weren't originally making him as a full playable character for a remake, and re7 was going for a different look. Plus he is older there. Let's see if they remake CV.
Hair color and style would make a difference.
Ada looks really good.
I think I'd go Ada, Leon, Jill, Claire, Chris.
I was in denial over it being Chris in RE7 until they datamined it to confirm it, so yeah I'd be pissed but at the same time not surprised.If they remake Code Veronica and it uses Nu-Chris' design with the only modification being his age, would people be pissed?
Anyway, I think Claire has the best design. Maybe tied with Leon. Ada and Jill are good too though.
