I am sure that recreating oneself while being autistsic is a far more difficult task than the process normies go through.
Recreating yourself as a mormy usually means making significant changes to your life style, like, changing jobs, moving to a new place, basically recreating a an environment where you can create a new sense of who you are.
I am not sure that relying on thinking to manage stimming would lead to any sort of recreation of self.
Because stimming is an unconscious process it is very difficult to control or suppress.
Maybe speak to your therapist about your ideas/thinking about how you would like to see changes in your life and how you might put that into action
