My general impression is that no school is going to accelerate a child based on the parent's telling them that they covered any curriculum even if it matched what's being taught. They always require some kind of validation be it a standardized test or an end-of-year material specific assessment. So you're almost certainly OK using whatever material that you want. When you reach that point I wouldn't even mention what curriculum was used just that your daughter has mastered the material and needs additional challenges.
That said, it seems like the number of posters whom have trouble making the adjustment to kindergarten is pretty high. Hopefully you'll be lucky but I'd enjoy pre-K while you're still there.
