I may be able to help run the photoshoot. I did so at a smaller Vocaloid photoshoot last year and it was fine, though a bit overwhelming because it was my first time. xD
After thinking for a while, I decided I'm going to wear my normal Luka costume to the photoshoot, since because I need fewer layers, it's much cooler than the red kimono one, and easier to dance in it.
Also, should we start organizing a time? I know it's early, so it's okay if nobody knows yet. I don't have any particular schedule for my costumes right now, really (Aside from wearing Magnet Luka at the Anime x Vocaloid cosplay on the night of Day 0), but does anyone else have a preference?
