The main thing is whether your setup is repeatable and works for you, but I guess if it was totally repeatable and totally working for you, you wouldn't be asking the question?
You say your string elbow is pointing toward 5 o'clock, but then you go on to say your "string forearm is in line." I can't reconcile these two statements. I can't visualize your string forearm being in line with the arrow unless it is pointing at 6 o'clock.
There are two ways to pull your elbow to 6 o'clock. One way is to continue to haul the arrow back by continuing to draw the bow. I can see where if you're doing this, you could end up with your string hand floating with nowhere to anchor. The second way is to use your back muscles to bring your shoulder blades together, which causes your elbow to move toward 6 o'clock without drawing the bow much, if any, more than it was drawn at 5 o'clock. The second way promotes back tension and a clean release.
It is possible that you might have to give up your finger on canine anchor in order to reach full draw. But you should be able to use the thumb behind your jawbone or some other anchor on your face.
