I think Luffy will strike her, enough to know that he can damage them. I do like the idea of Kid and Luffy both taking down "weakened" Yonko (aka, having final battles with with either after they have been attacked/damaged by others, its a war).
I also like the idea of Kid and Luffy remaining rivals until the EoS or towards the end where they fight. Idk we'll see.
The end of Wano will tell us heavily about the remainder of the series. Moreso I still wonder if any other factions of Rocks will be involved eventually, or if either Yonko have roles to play post Wano.
