Thanks for the suggestions but unfortunately the poisson-binomial distribution [1] is not a simple combination of those two distributions. It requires of specialized packages like PoissonBinomial[2] in R.

Ahh my apologies. Shows my lack of domain knowledge.

Looking at some child comments it looks like there have been attempts to get it added to scipy since 2016.
