The weekend of 10/8-9 looks not terrible for this idea. Full moon will be directly overhead right around 12:30 Sunday morning. The hardest part will be biding your time after getting in the Westside gate before it closes. 8 pm, iirc? Maybe a hibachi dinner in the parking lot then one or two short headlamp lines along the approach? But otherwise a well-bolted 5.4 seems like a prime low-visibility climb.
