I don't mean they would come back through Giselle Zombie powers, and I'm not sure that BG9 and Cang 100% dead. We didn't even see BG9 get slashed (plus we don't know what his K stands for) and Cang just got his right arm cut off and we didn't see anything after that.

It wouldn't be the first time, Kubo has made us believe he has killed someone off and later brought back, remember Byakyua, Jackie, Hallibel and Momo.
