Thanks for the chapter. Anyway, I hope you will continue to complete this series cuz I think this is a great novel I can tell it's better that some and for the plot we understand how hard to write this novel specially of lack of informations and we already expected this to be very different to the manga so I don't really have an issue in this. All I can say is just don't forget the most important information although you miss some you're not to blame since Oda just reveal it now.
With his subordinates all petrified, obviously Momonga wouldn't use Observation Haki to further provoke someone as arrogant as Hancock. If they were to face each other there because of this, all the other sailors would die and it is still a question whether he could win or not. Thanks for chapter author-san.
