If you are willing to spend the money, the weathertight bins are secure enough without the bungee cords and clips. They come with locking clips on all sides.

You can cover the lid with a towel to block out the light instead of using that.

I would make sure your bin is ventilated by adding holes on the lid

Providing 2 identical hides still apply to bins as well as glass tanks, unless you provide enough substrate for it to dig into (Some bp won't dig).
