To be honest... There should be some consequences or the whole postponing Jinbe at WCI makes no sense
1- Oda will not kill a Germa/Vinsmoke member without the presence of Sanji to witness it for Drama.. which excludes Germa from he picture...
2- I do not believe Jinbe's crew was annihilated when he cracks that big smile...
3- The ONLY LOGICAL death/sacrifice MIGHT be Alaadin who paved the way for Jinbe to leave at the end... So maybe that's the consequence... but generally it will only add depth and more backstory for Jinbe... nothing else
