Gender reveal pics in the snow?

So I live in Northern Minnesota and have my 20 week ultrasound on next Tuesday and hopefully they can see the anatomy of the baby, this will be our second, we have a boy who just turned 2. So I’m planning to have gender reveal pictures taken next weekend, I’d like to do it outside with the snowy background and the box of balloons for the gender reveal, although it’s supposed to be like 10 above. I wanna include our son in the picture as well. Have any of you taken gender reveal pic in the winter? Snow? That included the sibling? How did it go or turn out? Here’s a picture of the idea I’m looking at
