Chris Gee is the only one that seems to understand the problem. The OP said that the bow swings rapidly in the wind, meaning that it is going to swing to stb because of the wind from port. Combined with a hard prop walk to port in reverse it's going to be damn near impossible to get the boat to reverse to stb. If you walk the boat out as soon as you let go the bowline the wind will push the bow to stb, if you engage reverse it will make the problem worse. Back out of the fairway would be my conclusion, or doing a back and fill 270 degree turn if there is enough room. Backing into the slip is going to be difficult too because of the prop walk to port and the wind blowing the boat away from the finger. My boat also walks hard to port in reverse (three blade fixed wheel) and given this scenario I'd want lot's of
fenders on my port side if I had to back in.
