Last year we had to sprint for having the results at the deadline, and I think that we were not alone (I don't remember the details and I wouldn't like to name countries, either). We spent the first weeks preparing the images and transfering from flickr, and participation overwhelmed us, too. We will adapt to whatever date is agreed, and I'm sure countries from last year will be very alert for avoiding previous pitfalls, but as there are many new countries, I expect the same problems to arise again. How realistic is it, I suspect we will only know on September 30, when counting the provided images. As the international jury has a known pool size of 340 images (albeit a very good set), it may make more sense to give 3 weeks to the international jury and 4 for the local. But we can also keep the current dates and expand them if needed.
Best regards
