The idea of jumbling all the famous villains into one storyline is very risky, and it would be very hard to repeat the success of Arkham City. HOWEVER, the particular villains you mentioned do have unfinished stories that could definitely be integrated within the story of Power of Fear.

Killer Croc: Escaped Arkham city via the sewers, and has been hanging underneath the city since Arkham City. He was never caught, and therefore, was not moved to Arkham Asylum. Not only is his whereabouts unknown, but many mutilated corpses have been found floating in Gotham Bay, suggesting Croc is active and well.

Bane: After being aprehended by the GCPD from the Krank Co. Toys building in Arkham City, Bane has been moved to Arkham Asylum. His cell is guarded with an unprecedented amount of security, and he is watched 24/7. While he doesn't know what exactly is going on in Gotham City, he wants in. Bane isn't one to give up nicely.

Black Mask: Roman Sionis has been spotted multiple times around Wayne Tower. His intentions, and activities are unknown, but each time he has been seen with a backpack, that he leaves by the front door. The backpack is empty, and no traces of DNA can be found. This mysterious act has been done at least 12 times since he escaped from Arkham City.

Two-Face: Harvey Dent has been moved to a secure cell in Arkham Asylum, where he is watched 24/7. His actions within the cell suggest he is infuriated, rather than depressed. He has split his cell into two sides: on one side, the bed is always made neatly, there are no marks on the wall, and the area is kept completely clean at all times. On the other side, bits of paper are scattered all over the floor, and strange markings have been engraved in the wall. The markings are hard to make out, but one security guard claimed he say the image of a bat, suggesting he has moved his primary target from Catwoman, to Batman.
