TSoCP is just theoretical speculations, which means they don't actually program in anything. I can definitely fuse both PI and NEMEP databases, but I think that would work strangely, we would have to create a PI and NEMEP metagame. And there would also be several complications, for example, we would have to create a PI-only metagame, or a NEMEP-only metagame, or a NEMEP-based fusion metagame and more.
