Caity Lotz is fantastic, but I don't think I would've wanted Sara to end up as Oliver's love interest, because that's how she started, as a character created to be nothing more than an ephemeral dalliance for Oliver (and fridged to boot as a motivation for both Oliver and Laurel), and it seems it would cheapen all the growth she achieved beyond that ignominious beginning, and beyond Oliver's orbit.
Hmm... It's kind of ironic how two of the most popular characters in this comics-based franchise are original creations of the show, Sara and Diggle. Or maybe not so ironic, since it's happened with other original-to-adaptation characters like Harley Quinn, Chloe Sullivan, and Phil Coulson. Although it's odd that of those characters, Sara is the only one who hasn't yet been adapted back into the original comics (though the New 52 version of Chloe was in all of 5 issues). Her only adapted version to date is as a minor character in the Lego Batman 3 video game. (There was a pre-existing White Canary in a handful of Birds of Prey issues, but she was an unidentified Chinese woman and a foe of Black Canary.)
