The district I teach at (high school) is requiring two hours for kindergartners, three for 1st and 2nd graders, and 4 for all the rest. Everyone is done by noon, and teachers are there until three to answer any questions people have while working on assignments. I think for the lower levels, it definitely might be best. Though a coworker has a son starting kidnergarden in a neighboring district, and they're there from 8-2:30, with planned time for recess and lunch. However, they're only in the main class for 30 minutes at the beginning and the end, and then each kid goes into a small group instruction with an instructor, and gets one-on-one time. I'm interested to see how that will work out overall, as it sounds like it could be a good compromise if you can get enough instructors.
