Everything is possible; however, anyone considering this avenue should know that it is not as easy as it looks. There are many factors in making adjustments to SPF equipment that play a big role in properly proportioning all chemicals to make sure they adhere and react correctly to avoid inspection failure. Even application of foam is a skill built by practice. If you are considering this route to save a few dollars, it may very well cost you much more in the end. We strongly recommend that you let a professional handle this job. You will get what you pay for. Doing it right the first time is the way to go.
