If you can manage the commute, I'd try it. Many districts will allow you to apply to keep a child in a district where they started if you are willing to transport the child. You might want to look into making a formal request for her and see if you need to drive her all the way in or if there is a middle ground bus stop that would be able to take her part way.
In the long run, I think she should be as settled as possible by HS, when kids really get down to preparing for college and classes really build on another (which order the district offers Geometry and Algebra, what AP classes are offered, etc.).
