I had a theory for some time, that the doors in the Hat are much more than the once we saw. It wouldn't surprise me at all if the doors shifted and moved constantly, giving place for new portals. Perhaps every time someone jumps in the Hat, it automatically displays the set of doors he's most likely to want to use? Or perhaps, as utter says, they are limited to what we've seen and it can't travel to the other worlds.

Now, from what we've heard in Hat Trick, the same episode we saw the portal of doors, Jefferson says "how arrogant are you to think yours is the only one? There are infinite more. You have to open your mind. They touch one another, pressing up in a long line of lands. Each just as real as the last. All have their own rules."
