Being an AP teacher I talk to the AP (ETS) people on a regular basis. There is no way they CAN change that schedule. Earlier and they run into two problems. One is that there is not enough time to cover the matterial and two is that the places they use for grading are not available earlier. They can't move the dates later because a lot of schools would be closed by then. Plus they need time to grade the exams (it takes a couple of weeks believe it or not) in a timely manner so they can get the results to colleges and the like.
Personally the current Championship dates work great for me. It's during April vacation so I and my students do not miss school for it.
BTW I would think about running AP CS review sessions in Orlando if anyone was interested. Fat chance of many being interested in anything but robots there and then though.
