Even if it weren't painfully obvious what he would do should he gain this ability, there is no reason for him to eat it other than that specific comical value, based on the fighting style he has already developed. He is so quick that there is no reason for the fruit's sneak attack advantage. Saying that I don’t think he will eat any other fruit for the same reason (including the much debated mera-mera) unless it directly adds to his fighting style
and character. Keeping in mind part of his character is that he can swim, and amazingly well at that.
On a completely different note regarding this thread in general, there is actually a thread specifically made for questions like these meant to keep lots of little treads popping up all over the place. Maybe you just didn't see it but it's a sticky.

I don’t mean to sound mean but I'm sure you could get your answers there too and people won’t be upset with a ton of question threads when you can ask them in one... also it keeps good information all in one spot.

k:
I only said this because this is the second question thread of yours I've seen that could easily be questions that fit into that thread, and neither have sparked a long winded debate that would deem it necessary to make a whole thread on it if there is an existing thread made for those questions.
