I would be totally fine with it. I'm not 100% with the rules myself and for me story and role playing always trumps rules.
I always have me handy highlighter nearby when I go to prep the mods. And that's one thing that I can't stress enough. If you have the time, make sure you can prep. Although I never feel I've taken enough time to prep. (I'm GMing at GENCON...what am I doing online?)
In my experience as a PFS gm, players are eager to play and if you make a little slip up with the rules, they'll help you out.
