You are not an Arizona resident for tuition purposes, because you have not been in continuous residence for the past 12 months. I do not believe there is any way around that.
I have read your correspondence with Attorney Poulton and have considered the two theories you put forth. I agree with his analysis and conclusion that you do not have a strong case. There is no harm in arguing that case, just don't get your hopes up. You are not likely to be successful in convincing the state that you are a state resident.
