In Australia, that is illegal because it reduces the effectiveness of distribution transformers, the pole pigs in the USA. Further, putting diodes in series with the mains generates spikes that can cause EMI. You could follow your idea and not send DC back into the AC mains if you balance your use of diodes, so that always an even number is turned on and one half of the diodes are in reverse to the other half. You would still need to deal with the EMI.
