He already has. He's now queen of Level 5.5. Though since he's pretty much played his part in the series, and so has Impel down, I doubt we'll see him again. But here's my theory about him and Magellan:

Bentham probably didn't want to fight, or rather he didn't need to. He opened the gates, he let Luffy and everyone out, he's done his all the tasks he needed to. Fighting would be pointless, and Magellan just arrested him (also, fired the guy who pushed the button). He probably threw him down to Level 5 (out of his humilation), which would explain how Bentham got back to the tranny bar. However, because Magellan threw a prisoner down such a low level without a high enough bounty, he's been demoted to Vice Warden. Meaning Hannyabal finally got the promotion he wants, and everyone lives happily ever after.

Except Magellan. He got humiliated, demoted, and still has diarrhea.
