Near the end of Origins #12, Cal indicates that his ideal Blade Runner is one that will eventually break and begin fighting for the replicants. The top and bottom panels are clearly nods to Deckard and K, respectively, but I don't recognize the one in the middle. It doesn't look like Ash or Joseph, so we've run out of options for Blade Runners who become sympathetic toward replicants. That is, unless we consider Ray McCoy (I suppose it could look like him), but his allegiances are player choice, and the image in the panel doesn't immediately connect to him, unless I'm forgetting something.

So who is it? The only other possibilities I can think of is either just a generic representation of a Blade Runner or someone we haven't met before (possibly from an upcoming comic?).
