This sounds wonderful! What a great teacher. My only comment is that if the plan works, start getting something in writing so that it continues next year and beyond. The trouble with fabulous teachers is you can't clone them.
We had the good fortune to (eventually) get DS some individual, at-his-level pullouts in kindy, only to have them disappear when the teacher who was pulling him out switched roles and DS's grade skip required a school switch within the district. Oops - we didn't have anything in writing. It was a PIA to convince the next school that DS should not be getting the exact same 2nd grade math he had done in Kindy in pullouts.
I think you are in an especially good situation since the teacher has a special ed background. She will be a wonderful resource in helping to write up an IEP.
