Lately I had a theory, that between August 2015-March 2016, Lana wanted to do a deluxe or some kind of a special version (similar to Paradise) for Honeymoon. I know that Honeymoon was a vanity project but that kind of explains why she was making random songs during Summer/Autumn 2015 like Serene Queen or Cry Kill Die. She wanted to do a special version for Ultraviolence too and it later was formed as Honeymoon. I think Lust For Life album we know as today was formed after the end of her Festival Tour in August 2016/September 2016. Because I remember something that she recorded LFL with Abel in September 2016 (because he had a new haircut or something + they had recorded Stargirl and Party Monster in 2016 too).
