Hmmm, now B & V look like DIFFERENT GIRLS, rather than exactly the same but with different hair-color.
Yes, but neither one is attractive.
The key to going "realistic" is hiring an artist who can draw. Given the dearth of those (as evidenced by this image), this is not such a brilliant plan. Archie is the last holdover of a tradition where a stable of artists followed a "house style" closely, like Fawcett artists followed Beck's Captain Marvel model in the old days. And it's much easier for multiple artists to stick to a "look" that's highly stylized than one that's "realistic". Not to take anything away from the late Dan De Carlo, but I think it'd be easier to ape his style than, say, that of Neal Adams or Joe Kubert.
It's funny that even as superhero artists are increasingly copping out of learning anatomy by going all "cartoony," here's a strip that's been cartoony for 60 years deciding to get more "realistic."
