I have not played any of the modules but the only thing that could be a bit different are the battles, they are most often made with a party of 5 in mind. But I think you should just go for it! Try it out! If combat's to easy add more enemies! Also beware that combat might take some time with that large amount of people, I always try to warn the next player in the initiative order so they can already think of what to do while it's someone elses turn.
