As far as the art goes, I'm less concerned with exact likenesses and more concerned with panel to panel, page to page consistency. As long as Clark always looks like the same guy, I'm not worried if that guy looks exactly like Welling.
I liked Pare Perez and I've always liked Chris Cross. Other artists I wouldn't mind doing an arc would be Jamal Igle (who drew a big chunk of SUPERGIRL pre-Nu52) and Mike Norton (drew Green Arrow and Blue Beetle for a while).
And Brian Q. Miller needs to be chained to his desk.
