I still don't think this is a proper concept to promote even in fictional stories. However, if we must consider it, perhaps some stories might try to show the importance of communication within a relationship in an extreme way, but this is still a very unorthodox approach.
Most of the time, such stories are not associated with positive messages as they go against the core values of marriage. But hypothetically, a story could show that through the chaos of such an arrangement, the characters realize the value of their original relationship and return to a more traditional and committed state. But again, this is not a positive concept to begin with.
There are very few, if any, fictional stories about 'hot wife swap' that have a truly positive message. In general, we should look towards stories that uphold positive values like honesty, kindness, and commitment in relationships rather than this sort of controversial and unethical concept.
