When you are working with computers, and Linux in particular, what is possible and what is practical can be a long way apart. Even if you succeed, which is a very big if, in doing what you are attempting you will have an unstable, trouble prone kludge.
If you are willing to put this amount of time and effort into your system I would suggest that your time would be better spent consolidating and weeding through your data, off loading most or all of it onto some external storage, and reconstructing your system with proper Linux partitions and running a fresh install of Windows in a virtual machine. Currently most of your system runs on fat32 partitions and you are so storage bound that you are currently on the brink of disaster.
I am sure this is not the advice you want to hear but it is true non-the-less.
Insanity: Doing the same thing over and over and each time expecting a different result.
Democracy is 2 wolves and a lamb voting on the menu. Liberty is an armed lamb protesting the electoral outcome. A Republic negates the need for an armed protest.
