Ok, this is my weird idea. the way aquaclear filters work, seems like it'd be possible to attach plexiglass between the intake chamber and the media chamber to isolate them from each other, then put another piece of plexiglass in the bottom with small holes drilled in it, maybe covered with a screen. Now, just attach a prefilter and add fluidized bed media and you have yourself a self-contained FB filter!
