The most obvious issues with this is that the game boils down to predicting passenger patterns, but you're still just comparing two RNGs, which is one of the worst kinds of games. I also don't think this can be called Poker, really. Poker is an imperfect information game, where your hand tells you some information about your opponents' hands.
It would be interesting to read HN's ideas on how you can simulate the shared information part of the game in such a scenario.
