In theory, yes you could maybe self study for everything, but in reality no. Learning to fly is very complex and multi-faceted, some concepts are easy to understanding, others are rather abstract and difficult to understand. I think you will find that you need an instructor to help you understand many of the concepts. What you are asking is essentially the same as saying “Can I get a book about surgeries and then sit for the medical board at Harvard?”
Also, you will need a CFI to sign you off for several of the written exams. Furthermore, no CFI (including myself) would just accept a student’s word that they were “up to speed” because they had self taught everything, I would put you through a lot of my own ground school, all of which would cost you money.
Bottom line, this isn’t driver’s ED, learning to fly is tough and you will need formal instruction.
