If the majority of people on this forum haven't heard of Skulduggery, then it's not going to be bigger than Harry Potter. Just because some of the same crew members will be working on this film as well isn't going to guarantee the success of it, the success lies mostly in the plot. Any movies produced by the same production company will most likely (not always) have the same people working on it. Aside from the director and producer usually.
And Harry Potter has had time to brew (no potions pun intended). HP has been around since 1997, Skulduggery since 2007. Besides, lot's of horror isn't necessarily going to make a popular movie. The reason Harry Potter is so successful is because it appeals to all ages. Granted the later movie adaptations are getting quite dark, everyone still reads the books and at least the earlier movies. When you get a movie with a lot of horror in it, younger kids aren't going to want or be aloud to see it. Right there you've lost quite a large audience of people that harry Potter still can have.
Bottom line, this series isn't big enough and doesn't fall in the right genre to be more popular than Harry Potter.
EDIT: Having comedy, horror, and romance does always make it a good series. IMO I prefer action/adventure over horror, so not everyone likes the genres of Skulduggery.
