The only problem would be that the worlds would more than likely be tide locked to the dwarf and only a strip of the land would be actually habitable. The rest would be in a permanent ice age and a desert on opposite sides of the planet.

Of course, the view would be most impressive especially if the dwarf has an extensive rocky ring system.

I could imagine the planet/moon to tide locked to it's primary planet and still have all parts illuminated by the star.

Compare to our own moon. Only the extreme polar regions don't have a 'month' long day cycle.
