If he'd ended up as first officer, he'd likely have just been a commander (or possibly, though far less likely, lt. cmdr). I mean, in TNG and VOY, the first officers don't have any job OTHER than first officer. In DS9 Kira is first officer, but she's also the Bajoran liason officer to the Federation, which is a different sort of deal altogether. So first officer seems to be a somewhat more fluid role than most others.
