You're right in that she's not like the Zara we see from the /shudder/ NK arc, but we don't know what Zara would have been like if she'd been raised on Earth /shrug/. And it wasn't known that Lois was Zara until fairly late in the fic iirc.

Would be interesting either way to be sure. Lana as Zara would be interesting though it would depend, I'm sure, on your interpretation of Lana... And Lana's parents...
