The ND is a single out let and the 4 is four so no the ND will not work.

You do know that ball pythons are from a savanna right? and not a rain forest? A rain forest environment is not really appropriate for ball pythons, I know how appealing it looks but not really the right set up.

I know this is for a hognose but it might give you an idea or two. Hoggies and balls have very similar environmental needs.
