The idea is good, and difficult to pull off. I think you could go even a little bit more crazy with expressing stress, if you lose the sense of a clear rhythm this might be more clear. But when you start getting closer to order add some syncopation, the semiotic meaning of syncopation in classical music is in fact stress! You might want to put the piece in a different category, I would not classify this as Easy Listening - Classical. Maybe more in the experimental section ;)
