The only thing I can think of is reduce the size of the hole in the roof and ceiling. You would have add a layer of wood framing inside the existing framing for the exisiting hole to take it down to 14" x 14"; make the new framing flush with the roof and ceiling. The roof would have to have roof covering added to cover the new framing; 4" Eternabond could be used for that as long as there is close to a 2" overlap onto the existing roofing. The splice job on the ceiling could be covered with a trim ring of some kind.
