Recreating blue hour at noon

I’ll be shooting a scene soon where we need to recreate blue hour around noon. My main approach is to work with very soft light while keeping defined shadows, and to underexpose by about one stop (being conservative, with the option to go darker in post if needed). I also plan to cool the image by adjusting the camera’s color temperature.

According to the forecast it will be overcast, which helps a lot in terms of having soft ambient light. From there, I plan to use plenty of negative fill and a polarizer to control reflections and reduce unwanted highlights.

I’ll be shooting with the Sony Venice at its base ISO of 500.

I’m not sure if this is the right approach, or if there’s a better way to achieve this that someone with more experience might suggest.
