There is a limit of 1200 images per job with the camera GPS workflow, but that should be enough to cover 200 acres even flying pretty low at 60 m and getting 70% overlap.
If your images have tags, which with a DJI aircraft they do, you should be using the camera GPS workflow instead of the stitch only anyway. It will help keep things aligned so you don't have to handle the rotation.
