Yes, you could. There is a section in here that speaks to the intent and about prosecuting the complainant and what would be required to do so, which I think just restates the law as it presently exists. However, you could also carve out exceptions and circumstances under which someone should never be prosecuted.
You could carve out an exception to never prosecute a complainant at all. Some would say that might go too far because there may be situations where there are multiple complainants and the public good would require that someone have a ban when they might personally not have wanted one.
