I think PS as a TV serial will be a disaster. It is most likely to follow the same limited dialog driven path of many other historical and mythological serials like Ramayana, Mahabaratha, Swami Ayappan etc. The intricate thoughts and nuances of the characters so effectively etched by kalki will be totally lost.
Animated films of all 5 parts will something that can be seriously considered; in the absence of the possibility of credible movies happening. By making high quality animated films, we can overcome the limitations of actors and actresses. It will also retain a certain scope for imagination for the viewers, like the books do.
