Personalized recommender system? No, not doable. This requires separate setup, model serving, regular retraining since typical collaborative filtering does not support adding users and items. Besides, it makes no sense if you don't have prior data.

However, implementing popularity-based system, without personalization, is possible. This is typically just simple Bayesian statistics, doable in 10-15 lines of Python. See e.g.:
