OK, I don't singlehand. But if I were faced with that situation, I would rely on that windward piling and I wouldn't bother to turn. If you could come down the fairway until you had that first piling next to the cockpit, from there you could slip a line over it. I think that would give you windward control. Then maybe walk the line to the bow and slip it around the stbd cleat. Keep holding onto the end, go back to the cockpit and motor in while controlling the bow with your line.
The boat, because of its length vs. slip width, couldn't make the turn into my slip if you wait until the windward piling of my slip is next to the cockpit. However, you do as you mention if the line was put over at the windward piling on third slip upwind. This would hold the boat so the bow could be worked down to the windward piling of my slip, appropriate lines for my slip placed, and then the original line on the third slip piling released and recovered, as the boat starts into its own slip. In my case, that would be a possibility currently as no boats extend into the fairway of these ajacent two slips. The tricky part of this is that the crosswind is trying to blow you off these pilings and across the slip. Definitely something to think about.
