@Idolse, that is an interesting idea. I did a few days ago briefly think about some kind of "duplicate author variations" function in the plugin, but put it back in the mind because of the issues of the library view being only suitable for showing books not aggregations.
Perhaps it would be better to treat this situation as its own special case - with its own dialog and resolution approach. Certainly I will hold off doing anything related to it until I get more time to think through some approaches. It may be that we can fit it into the existing search approach or that it requires something different. You would certainly need to have an equivalent of "ignore title, fuzzy author" so that you could catch where two variations of the same author each have a distinct set of books in your library that none of the existing algorithms would catch
