It mostly works, save for a layout thing in the city center/temple. I have Vhis somewhere specific, which has to do with the location of the Toa stone. Hura's as likely to follow them to either keep them out of trouble or just out of curiosity. Hura's fairly timid, but he'd be as likely to wonder if what they're saying is valid as he would be to seek a somewhat more quiet place to view the Red Star, since the crowd might be a bit too much for him.
Also, the climax isn't midnight, it's nighftall/just after sunset. That's when the Red Star appears. Quicktip, we should have our characters be at where the Toa Stone should be before then, or get there just at nightfall.
