That sounds like a nice idea for a game with all these different variables to account for, maybe you could try to make it in more time because 3h seems too little for such a project.
I believe with another hour it was doable to randomize wind and box mass because its only internal physics number randomization, but I wouldn't have time for much playtesting however. I had less than 2 hours to make this because the jam deadline was almost over then. :)
