Perhaps I misunderstand, but I think what you're calling "faith," is simply confidence level. Renaming it "faith," I think, is going to muddle the terminology more than it assists the ability to argue the point.

Let's take your view of evolution: You're saying you accept it based 1% on faith. I would say that I am 99% confident of it (assuming your view), which has the advantage that doubts that enter into the analysis would reduce my confidence level, but not increase my faith level, which would remain at zero.

Nor do I believe that this renaming helps us meet the divergent views between the faithful and the evidence-based. To give credence to faith as a necessary filler of doubt doesn't help move people toward evidence, in my view. Further, it is exactly the sort of logic the faithful cite - science is just faith in something else.
