I suppose it's possible to dream up a context for it, but the realistic answer is 'no'.

By the way, you don't "wander" about this - you "wonder" about this.

A person has not been nice to me lately but he still asked me for a favor, could I say "I'm so going to not dp that for you." as if I was trying to emphize my unwillingness of not doing him a favor?

As I have said more than once before, it is possible to say almost anything in English, especially if the stress and intonation are appropriate. I would not recommend it, however. A far more natural way of saying it would be, " I am not going to do that for you".
