They would always survive, do they really think the 5 would die for HAKAI?
And who would be the new protagonist? The curiel, which resists LAKAINU's MAGMA with basic COA.
KID is simply not out because BM did not use ACOA with ADCOC.
KAIDO just didn't do 1x5, because Luffy awakened the necessary strength to fight him at the last minute, and even so KAIDO put LORO to sleep and LAW on the floor for 50 seconds, Kid and Killer wouldn't be a problem for KAIDO, either two failed to do anything versus KAIDO, and it was KID himself who suggested it, listen well, never that the 5 SNS without Luffy possessing or awakening ADCOC with just their standard ACOA, FS and COC would have a chance against KAIDO or BM, even individually. As ZORO said before using ADCOC unintentionally, it would only wear out and in the end lose to KAIDO 1x5.
They only managed to do something after the ADCOC was awakened, LORO KAIDO (small cut) and Luffy is there trying to win, all thanks to ADCOC, before ADCOC was superficial blows, they would lose, this is the reality of things, KAIDO would do 1x5.
