0Hi,02br 02br 00I think they are not suitable in the context you gave because changing 'may not' with 'might not' in your context puts a different flavor to the sentences. Although at the first glance it mainly seems to carry the notion of giving permission to do something, 'may not' has a hint of ordering in your case and that is the kind of impression, I think, any person using a sentence with 'may not' wants to make. I would go further and say that I think it is wrong to say 'You 01u 00might not do02u 00 somethng' to say what I think you wanted to say.
