One of the issues is that a permit is needed for any burn in excess of 20 acres in size and those require certain conditions etc which sometimes are hard to meet in advance. What needs to be done is to get with the DWR at burn time and provide them with manpower. If there was sufficient manpower, fire lines could be created and a series of 20 acre plots burned in a single day. With enough men and equipment I believe several hundred acres could be burned in a day safely. However that is going to require probably a minimum of 50 people willing to devote a day to help. I do have some experience in controlled burns having done some of them in college and work.
