Sigil should handle loading it. I would suggest doing a FlightCrew validation on it once it's loaded. After you fix anything FC found, save it and give it a run through ePubCheck 3.0 and then fix anything found there. If you think it could be done, check it with ADE to see how it looks. You can either use the desktop ADE or Bluefire Reader for iOS as Bluefire is based around ADE.
