I'm doing what I can to prepare (weather considerations, reading trail reports, and of course studying the photos from hikers who have done the route very recently).
Let us know how it works as far as route-finding, and whether the route is fairly obvious using the reports and photos, etc. I've considered doing this route instead of the main trail, but since it would possibly be a solo hike and I'd be finding the route using the tips, reports, and photos, I'm still unsure of whether to do that, or just stick to the main trail and hope for a permit to be available. Since the route is new to you and you're using a similar strategy, it would be helpful to know how it worked out.
