Yes, a highly flexible public school can work, but you're pretty much going to need EVERY accommodation/differentiation tool in the arsenal, and probably right up to the edge of what seems possible.
As long as you have a school that is focused on "what does this student need" and not "we do X, and Y, and sometimes Z, but never A," then it is possible.
It's not going to be perfect, in all likelihood. The one advantage that public school has over private is that they are more accustomed (via special ed) to feeling that the student NEED drives the arrangement, not that you have to choose from their a la carte menu, and take it or leave it.
