Technically, unless Kaidou´s weapon is really made out of seastone, Luffy should not have a chance against Kaidou even with the training.
Him being able to hurt Kaidou now is not equal to him himself taking hits better.

I think he has potential to destroy the club . On hindsight kidd and killer will distract big mom .
That leaves zoro unless he fails to arrive then luffy will be fighting kaido alone for time being.
There is good chance luffy will struggle using his advanced coA but he wont be one shot.
