Smallville Supergirl?

Ausiello from TV Guide's latest on Smallville -

Question: Any news on the type of person (age, looks, etc) the CW wants for Supergirl on Smallville?— Nicole
Ausiello: KryptonSite has a detailed casting breakdown, but basically they're looking for an actress who has blonde hair and can pass for 19. Also — and you didn't hear this from me — the hope is that Supergirl will eventually be spun off into her own CW show. But again, you didn't hear that from me.
Question: Is there any truth to the rumor that Smallville is trying to get Kristen Bell to play Supergirl?— Jason
Ausiello: That sounds suspiciously like the sort of baseless rumor I'd start. As awesome as that would be, there's no way KB would take a supporting role at this stage of her career. And, really, who can blame her? The girl's on fire!
Question: Any news on who'll play the new editor of the "Daily Planet" on Smallville (Ausiello Report 6/4)?— Justin
Ausiello: I'll tell you who won't be playing him: the erstwhile Clark Kent Dean Cain. "Interestingly, we want to have Dean on the show this year, but I doubt it's going to be in this role," exec producer Al Gough told my colleague Rich Sands. "We had thought about it, but I don't think we can make that work for a number of reasons, none of which, by the way, are creative. It's scheduling, financial, things like that. But the plan is to have Dean Cain on the show this year." So who is Gough eyeing to play the "Planet" boss? "We'd love to stunt-cast it with a great person, and we're going to audition for that."
