I think it would be an amazing comeback if LEGO would re-produce some more LEGO Harry Potter set's. The Ministry of Magic Atrium and Grimmauld Place for instance. I would love LEGO to make a LEGO Grimmauld Place, in the hope for a LEGO ''Kreacher'' Mini-figure, and maybe even some new Mini-figures, Accessories and Building Techniques.
Not only is it a memorable place in the Harry Potter series, but would also be a great rendition as a UCS Model like the ''Diagon Alley'' set.
(NOTE- LEGO if this does pass, can you please possibly make the Kreacher head mold in your Denmark Headquarters, Thank you)
