Maybe... Perhaps a number of the those NPC's (Fujin, Sareena, Bo Rai Cho, etc) will return in the future with a more prominant role or playable if lucky (there's potenial for like Sareena as a hero now that she's no longer under Quan Chi's control and since he's dead) if they become more popular enough in the future due to their MKX appearances. Or some of them could be DLC characters for this game outside the season pass (like how Injustice had a couple characters that were released much later than what was included in its season pass).

If boring Tanya was popular enough to become DLC, any of them are possible.
