Can I make these wings ahead of time?

It sure looks like these would be a good candidate for day-ahead preparation.

It appears that you have two options: A.) you could proceed through step 4 (the first roast) and pause (which is probably what a restaurant might do), or B.) you could proceed all the way through step 6 (through the second roast).

My guess is that Option A would provide the best end result and Option B would be the more convenient process.
